For every completed drawing, there are probably 4 or 5 sketches drawn - normally these are drawn on cheap printer paper and thrown away once i'm done with them (or sometimes even given to children at shows to colour in!). Some of them never make it to the 50-hour drawing board, like the sketch on the left.
I've always wondered if I could do anything with these sketches, so the last two I did, I made sure they were on my usual quality drawing paper and I spent a little extra time on them than is normally necessary (they are usually only used to give me an idea of composition and how I plan to tackle the full drawing) - probably an hour each, rather than the 50 hours for a full drawing.
Anyway, here are two of them, both image size around 8x10". I thought i'd frame one to see how it looked.
