Nate Bellegarde is -- well, I have to confess, I didn't know who Nate Bellegarde is up until yesterday, when I ran into his Elongated Man request. A little googling showed me that he's a really talented artist with a mix of superhero style with and indie vibe (or at least that's my take). He's a pro since he was 16, which means he is also a natural with uncanny talent.
The best thing about him is that for $5.00 USD, he'll take requests at his... "Sketchblog". No. Wait... That's "Bletchskog" (nice trick!). I'm already negotiating a challenge for him (and so should you).
His Ralph is one of the best I've ever seen, he really looks like a rubber man and his insightful expression is spot-on.
