Here's something I knocked up in Skincraft in about 3 minutes - Next to no effort has gone into this, so don't try and emulate or copy it or anything, but it should illustrate what I mean a little better.
But yeah, take your time - If it's too challenging for you though, don't worry about it and I'll find an alternative. You're not obliged to make one - You've already helped a lot by making what you've made already. It's just that you seem to be really good at skin making.
EDIT 2: You can also play around with the angle on the arms.
