Thanks for the feedback! I think that the problem you mentioned is caused by the really bad and quick normal map i made, but don't worry, i am working on that. I will take what both of you have said into account and make amends. Here is a quick and dirty scanline render with diffuse only.
Protip: Scanline render is kind of lame, use screengrabs. Also, render onto grey background not black or white. Also, try not to paint light info (highlights) into the diffuse. It would be neat tho, to see a donkeykong style barrel like this done next gen. Take it to the next level and model out the boards and metel in…
