O.K, I think it's about time for my feedback...
Heroes and Cons: I like the concept, but I think you need to enhance the Bug aspect a little more. After all, Bug is the primary typing. Also, how about making the body parts seem less like objects? (The body in particular looks a little weird with the perfect 3D view.)
CBMeadow: I really like this design, and it's one of the favourites. I'm a bit sceptical about the feather though; it seems tacky and an add-on. How about taking away the feather, as it still looks Psychic due to the orbs.
WPS: Heh, the design is adorable, although underwhelming. How about adding more detail? The main problem I have with this is the fact that it's another spider.
Mari: Although a cool concept, it seems a little inferior to some of the other designs. I'd probably scratch it, and think of something more inventive :)
akela: Ummm.... I'm really doubtful of this concept to be honest, and the artwork doesn't do this much justice. As I said to Mari, scratch it and think up something you'd see as a pokemon.
Yilx: Although I was sceptical of that Oracle Bug at first, and I wanted you to go with the Scorpion, I'm now really liking this pokemon. I disagree with the others; the colour scheme is perfect as it is. I'm unsure of what those balls near the antenna are.. how about replacing them with orbs attatched to the antenna, in the middle or something?
Nov: I'm going to be honest here: I'd do another design. It looks a tad humanoid and unusual, especially for a Pokemon. I know you can do better!
TeraVolt: Although I was unsure at first, I saw the light and realised how brilliant this Pokemon is. I get the Lunatone reference too, a nice addition.
EmpoleonGuru: Umm... an...odd design. I really can't see this as a pokemon though. It looks like you've stuck a person's head on a caterpillar's face. Sorry.
Koa: One of the best designs out there thus far, it's an amazing concept, with a good colour scheme, and nice art.
B.Reinquist: It looks a little too much like Kricketune for my liking. And I doubt the intricate body pattern could be sprited efficiently. A good concept nevertheless.
Rittercat: This looks great, although not that original (not your fault, just the amount of people who have decided that a bug with orbs or turbans will work well). How about "evolving" the desig so it looks more fully evolved. Right now it looks like a pre-evo.
Orivexes: Although edging extremely close to the "Bug and human together" section (which I evidently dislike), I love the concept and feel of the Pokemon.I'm unsure about the feet however. I can't properly judge this until it's fleshed out in colour.
Asylum Rhapsody: I'm not digging the concept thus far, but I'm sure other people would disagree. To me, it looks a bit like Bug/Ghost.
DougJustDoug: Oh wow. I love this concept, and I really hope you continue with this, and add colour. Nothing much to say.
Calad: Awww... a great concept, but my main concern is that it doesn't look fully evolved, like Ritter's.
Espeon65: I suggest sitting this one out and learning different drawing techniques first, before submitting. I don't want people to shoot you down and say that it's terrible. That's my job.
Darklatias92: This looks so amazing... but for the wrong typing. It suits Bug/Flying to me, sorry.
CyzirVisheen: I'd start a new design. Sorry, but it looks too much like Heracross, and a bit too bulky for what the stats will imminently provide.
Mos-Quitoxe: Eek, I'm a harsh critic. To be honest, I don't like either of your three designs. The top left is confusing and too intricate, the bottom left looks strikingly like Mollux, and is a little too bulky and doesn't stand out, and the bottom right is... I have no idea what that is. You have so much potential: use it!
Furosuto: I don't like this concept at the moment... it looks more Grass or Dragon than Bug, and the eyeballs seem a bit tacky.
aragornbird: Nice idea, although a little too simple. I love the colour scheme however.
Quanyails: This is actually pretty good. I love how you've integrated the Psychic typing, whilst still leaving it subtle. I'm especially fond of the expression and postion, which backs up the Fortune Teller feel.
Birkal: To be honest, the concept isn't great. It looks to me like a cockroach with a magic suit and a wand. I think you can do better!
I've just realised that I've become progressively harsher. Anyways, in no particular order, my favourites are:
