I did some overall updates. Still not quite satisfied with it. One problem is that it seems to be impossible to make the studs or the cleats (whatever you call it) in seperate colors, so at the moment they are all white'ish.
So, here it is. My first work. I had a lot of help by using a texture made by Patrichos, and if it looks familiar to you, that's why. Many thanks to Patrichos for letting me use his texture as some kind of base I will try to make my own textures in the future, but for now, enjoy this one!
