I had a streak of luck long ago with producing some good art. Recently I've had a streak of luck producing some good game music. Switching around between what my primary focus in game development is tends to get weird for me.

I'm feeling like getting in to pixel art heavily now. However, I'm not sure what size I really want my canvas to be. I'll be starting off with Gimp (leaving Paint .NET) and I'll try making some random stuff for BYOND. Just to get the feel of creativity again.

My question is, how should I build myself up and what would be a good canvas size? Any techniques I should also apply to get the best amount of details in?
