I really wish my artistic skillz could encompass the Manga Leather Effect. It's that shiny, wow-that-must-cut-off-circulation look to anything made of leather that you see in manga. Kaori Yuki does it remarkably well; just look at any scans of her Angel Sanctuary artbooks, and you'll see what I mean. Setsuna's pants are usually excellent examples of this. I just like the way it looks on gloves and jackets and whatnot...though it does, admittedly, look more than a little obscene most of the time.

Still. Being able to draw leather is a skill the world needs more of.
