It's the whole thing that you should be focusing on.
Well then that's a problem. Focal points are a basic skill for all artists.
Btw, the reason people tend to focus on the wings as mentioned earlier is because it has less of those lines on it. Instead of being a mess, the wing is a pretty shade of red with less ugly line clusterforgetage. the color in the wings are more evident because it's not as riddled in multishade grey lines.
another big problem is that it's very hard to distinguish one part from another around the right hand area. you really have to focus in order to discern when the jaw ends and when the hand begins, and I didn't even notice the other wing until later on. That wing doesn't even look like it's attached to the rest of the munster.
Oops, ment to hit preview.
if I could make you do any 3 things to this drawing, it'd be:
making smoother, cleaner lines that were only 1 color.
Make it where the wing flesh is a different color than the rest (unless the wings are just supposed to be giant, extremely flat bones, which I hope they aren't)
make a focal point.
whenever I look at this, I find my eyes just wondering about, not wanting to focus on this picture and instead save themselves the ache.
