I am doing this to see what the range in age for wincustomize users. I think in a way it would help me in my future skinning
Not a bad approach if you looking to just skin for one segment of the community.
You can go through a lot of posts in the forums and see the same advice always given. Do skins for yourself, and upload them when you think you have done a good job. Remember we are always our own worst critics.
If you like what you have done, I bet most people that view it will also. No, I'm not a skinner, just a person that can appreciate the hard work that you folks do.
