I'd join in!

I can't draw a lick, but I would be super interested in a thread like this.

Might even submit my terrabad MS Paint drawings of Blitz and Heimer's heads for lols. (Beware, simple shapes and no shading, inc >.<). Provided this becomes a thing of course.

Hells to the yes.

If it means we get a new theme like Pulsefire Ezreal for Lux, it's the best idea ever. Am I barking up the wrong tree? Has the next theme already been announced?

Absolutely, I'm all about even more communication between Riot and its community.

Very much so.

Would be awesome

I like art. Artwise, I like the level that Riot displays, too.
I like your proposition, looking forward to it!

Yessss, I don't consider myself an artist but I'd still like some opinions on my drawings

Holy moly, that would be an amazing opportunity. I wouldn't be participating, my art is still in its infantile stages, but I still have to vote yes. Critique and paintovers from industry professionals? Yes please.
