Recently I've been doing some background work for a 2D college project. Since this is my first time doing backgrounds I did some thumbnails to record the process and to see what can I do better next time. With that said, one of the things I can easily point out, is how much time I lose by not keeping and order while working on my layers. I just go back and forward too many times. And my lightning and shadowing should come after I'm done with my values.
