Well art is subjective, so here's my opinions on what's presented:
CONTESTS:
MAC #24: Retyping:
1st Place: A Fighting-type Stunfisk? Interesting combination though I'm surprised how well it works together. It looks like it would have an interesting fighting style, considering its face is on the other side of its body so it'll probably be constantly bending all over the place to not only see what it's doing but also spot any weaknesses. I also like the red "!" on its body, as if it's warning you it's about ready to make your flop like a fish.
2nd Place: So it seems like no matter what form Bronzong takes it'll always look a bit creepy, good to know. Anyway, who doesn't love a metal dinosaur? I'm sure if this Steel/Dragon Bronzong was a real Pokemon that about half of them would be named "Grimlock". Anyway very nice piece, at a quick glance you could easily mistake it for just being a pure Dragon with some glowing bits, it's not till you look closer do you see it's actually mechanical in nature. It also does a good job looking ancient, like ancient people tried recreating a Tyrantrum after finding a skeleton of one.
MAC #25: Pokemon Trainers:
1st Place: A bittersweet picture. It's sad to think that Youngster Joey would become homeless, but every cloud has its silver lining and though the world might have abandoned him, his Rattata hasn't! The vast amount of detail is also nice, making you feel like you're in an actual city alleyway (well, one in a Noir film being there's no color). In addition of drawing the bricks there's also texture, cracks, and gaps. The garbage can's lid is open revealing garbage bags. You can see that some windows have drapes while others don't (and possibly a face looking outside one). There's words on signs, poster, and graffiti on the wall. Even the ground has details like the cardboard Joey is sitting on and a grate which a faucet is dripping water into. And of course the design of Joey shows his homelessness but also a small smile as he looks upon his sleeping Rattata.
2nd Place: A nice looking piece, that trainer definitely looks like someone who would use Dragon-types like Haxorus. Haxorus was given addition detail to make its yellow parts looks more scaly which I would say worked nicely. The main display on the trainer is his face which is very anime: triangular face, wild spiky hair (though it sort of reminds me of N's hair), and eyes which look a bit unnatural. Sadly that's all there is except for a lot of green, but the artist did a good job making the trainer and Haxorus stand out with thick lines and bold colors.
MAC #26 - Mega Evolutions:
1st Place: Not a bad Mega Kingler, I like the design of the head though that's really all I can say. Okay, true, Kingler pretty much IS just a head with skinny feet and two claws, but still it feels like more could have been done to make it a bit more distinguished from normal Kingler. I don't know, I just look at the claws and think more could have been one with them. And yes I see the big one has been enhanced a bit, it's not that much of a difference (though I do like that "tooth" on its side).
2nd Place: A piece more about the post rather then the Mega Evolution, which is rather lacking. Mega Raikou more looks like a sort of "Primal Raikou" with it not really changing its shape while having several parts of its body now glowing. The artist makes the colors stand out and blend together real nicely, though if GameFreak was to reveal this as Mega Raikou I'd be a bit disappointed. But as I said, this piece is about the pose and what a pose it is. Raikou standing tall and proud amongst a fierce thunderstorm, its cloudy mane blowing and charged with electricity as it stands atop what looks to be stone ruins. Though he didn't do much with its design, you'd still probably run away from it if you saw this thing standing in a middle of a storm which it might have created.
NEW ARTIST: Blue Frog
The two pieces shown here shows he has a nice range of styles.
The first picture at first looks just like a plain group shot of all the blue frog Pokemon, but close inspection would reveal it has a bit or personality to it, mostly comedic. Greninja's tongue is laying across Politoed's head (though it doesn't seem to mind), Toxicroak wants you to draw him like your Kalos girls, Croagunk doesn't look like he's having much fun, Poliwhirl is trying to get a better look over the crowd, and Froakie seems tired as Frogadier looks at it bemused.
However he also can do nice stylized work as shown with a stain glass window-like Volcarona piece. Each part is separated by a nice thick line as they fit together to form a Volcarona flying up to the clouds as flames surround it. At least I think, to be honest it is kind of hard to tell what the orange parts on the clouds are suppose to be and I have no clue what's that suppose to be on the top left. However it's still a nice piece that you might see in a place worshiping Volcarona (it can be used as a substitute sun, afterall).
