Well this is the longest I've spent on any drawing on my computer. The hardest part for me about digital drawing is the unlimited possibilities it affords me. Complete freedom is very constricting? Being able to zoom in and draw on a very small scale suits me very well, and it is frequently surprising how smooth the shading looks upon returning to a normal perspective. It is just difficult to keep in mind that the drawing will usually only be viewed from a very zoomed out shrunken perspective and all the smooth little details sort of blend together into an unidentifiable mess when viewed like this. But, as long as its fun it doesn't matter eh?
