Edited again, kinda hard doing this in five minutes spurts through out the day. Gets confusing.
Edit: Candiru, I find it hard to draw examples of improvements from your edit, because my attention is too diverted by some flaws in the edit.
Here's my hand @_@ Perhaps I have strange finger to thumb proportions. The angle is different and it becomes evident that some anatomy is wrong in my artwork, but I'm not going for 100% realism, I just want it to look like a realistic looking hand.
Sorry for the large image 56kers
