I have been playing around with my new toy (GIMP) plenty lately and have one new drawing to post.
Don't worry, I'll (probably) clean it up eventually. This is certainly the most accurate drawing of Bumblebee I've ever done.
Also, lately I've bee working on building World 1-1 of Super Mario Bros. in 3D. I've nearly completed it, here's a far zoomed out shot of the whole thing:
Basically what I have left to do is add the bushes, the Item Blocks and update the textures' colours. I started this before I had GIMP and am just using public domain textures I found online so until now I didn't have a decent tool to modify the colour of the textures.
