Hey guys. I'm currently working on a huge background of my indy company website and found myself struggling quite a bit on it. My intent on letting so many space up to the sky is that I'm probably adding more elements there. The original canvas has 4000x6000 dimensions which I'm willing to enrich with details. Could you guys point me out few directions here? I can tell it needs texture at some point, since I'm not sure if I'll keep the innocent line stle for much longer. Book references that could help me out are deeeeply appreciated too.
