I think the problem I've been having with creating art recently is that I'm trying too hard to get it "ready" to see.

Do I really need to set the lights up perfectly for the very first image I post?
Do I really need to have all the textures accurate that soon?
Must I take all effects into account this early in the scene's life?

I think I should try, just once, to start on the objects' shapes first.
For the first few steps, just work on the how the objects are shaped.

Don't care what colour they are, how they're lit, what effects are applied, just the shape.

Then slowly (and I do mean slowly) add colours and textures, then lighting, then effects.

Maybe I'll be able to get another scene out faster...
