It's not like you get to look at it a lot while racing either, all you see is part of the bonnet maybe.
I've made quite a few skins myself, and you know how many I have used? Maybe 1 or 2. Hell, I don't even have most of them in my lfs skins folder. I like making skins, designing, working with photoshop etc. If he is into graphics, design, wants to learn and practice making skins, then why not.
