Any critics for my mousepads plz?

[L-e-x-x]

Well, hello, crowd!
I've always liked modding, especially custom mousepads, and recently i've started making really lots lots lots of them. Either do them for free - just for my friends, or it's like smb says "you know, a friend of mine has a birthday soon, and i have no damn idea what to offer" - so here's where i come into play.
Could you please give me some good critics on my pads - what's OK, what can be done better, and so on.
All the pads are USB powered, they have hard plastic coating, so it isn't that easy to scratch. They also have silicone pads on the rear side, so they don't slide.

Thanks in advance
