Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I don't know if it's good enough for you guys. The excess smoke can be used for like head lines or something. I kinda made the "The Smog" blend in with the smog (lol?). Oh well.
Cartoons! I prefer the second one of yours, with the 'O' on the same level as the other letters. It's very simple, yet effective and looks great.
CactuarJoe, yours is good because that's actually the same idea I first had when thinking of a logo. Though I was thinking of Koffing actually blowing out the smog.
CactuarJoe's are cool, but #2 would probably be way too big and intrusive.. his #3 is really cool though.
Cartoons' looks more like an actual magazine title though. I personally think it would be cool if the "o" was yellow like it is on Koffing's stomach (while keeping the rest of the letters purple of course). Also think the o looks better uneven from the rest of the letters. It's like that trendy lowercase i stuff that apple and many others do.
Edit: Also for cartoons, the S is cool looking and all, but there's something about it that is bothering me... Is it thicker on top than on bottom? If my eyes aren't deceiving me, is there a way you could possibly make it more symmetrical?
I opened up photoshop about to create a text-based logo almost exactly like Firestorm's second, but I decided to check the thread first. Good thing I did. So far I like Firestorm's second, Cartoons' second, and CactuarJoe's second.
I love the idea of Alakazam reading the magazine, extremely original xD
KoA's one is plain awesome and cool, it looks incredible.
CactuarJoe's idea is cool too, and i like the one where Koffing is flying rather than the other one, its a great idea.
CactuarJoe's second one is probably my favorite so far.
I was going to say that, imo, the logo shouldn't use Sugimori or any other existing art as a base. Having said that I think Firestorm's is very cool even though the Koffing comes from someplace else (Or if it didn't, bravo!) I also like Cartoons' second one a lot.
