The one thing most people do when making a skin is they put to much efort into it. So when they get one download on their skin that they took 30 min on, they flip out. That's why I don't take that long to make a skin. I make it simple and usuale get 9 to 10 downloads. I was lucky to get  89 downloads on my jake the dog skin(Jake the Dog link here). I didn't take an hour or half an hour to make that skin it took me like.....3 min. Just do what you can on your skin, it dosen't have to be perfect. You need to learn from your mistakes. So take what you can take, even if you think your work is terible.  We arn't all perfect,and we are all different. So make your skins and be proud of who you are and what you made. :)
