Concept art for Verne on Vacation, an animated pilot (Cartoon Network, 2009) that recently got picked up as a series (or is it a film?). HERE’s a 3min sample. (always interesting to see completely different genres hybridize like that!)

From Marc’s site: (abbreviated)

Sylvain Marc is a French artist with over 15yrs experience in animation. His practice ranges from art direction and visual development to character design, direction, 2D/3D animation, storyboard, illustration, and comics. He’s worked with well over a dozen major studios so far.

When he’s not doing art, you’ll find him gardening, planting trees, tending to his four sheep, dozen hens and four cats or building a ram pump to bring water up to his veggie garden on a hill of the Basque countryside.

I find his art witty, wonderful, lively, lushly-detailed, and thoroughly playful.

He’s not listed on LBK yet, but here’s his site:
