Good start. It's easier to draw your own hand, just keep practicing, doing studies, and all that. I think if you cleaned it up a little and angled the wrist down a little more it would look better. If you're using a tablet and some sort of painting program, use layers, that way your sketch doesn't blend in with your color.
If you are practicing hands this is an okay effort.
Like others have said it is at quite an odd angle, as if it is broken or something.
The glove takes away from it a lot as well.
The only thing that really bugs me is that it looks like you went and demolished it with the blur tool. xp
