As a Tomb Raider fan from the first game, I can say this is one of the most beautiful fan arts I've ever seen. When I saw this it took me some time to understand it was a drawing and not a 3D render, you did a very good work **
It's a bit too soft for my liking (almost looks a bit blurry) but except for that it's awesome. Looks like it was print-screened directly out of the trailer. And that broken porcelain effect at the bottom is extremely stylish!
