I usually like to, depending on the type of drawing, break it into parts to work each day, 1 day I do the sketch, another the line art, and other I do the coloring for example. I thought I could finish everything this weekend, on this one I've only managed to finish the ship... it was annoying :U
I think next one things will go much smoother tho, I probably won't be able to finish the 2 pages next week, most likely the line art of the rest of the background assets. The rest is easy~
