Thanks for you reply, i think the problem is the program im using, Paint.net "blures" the logos, and they look like bad quality, i dont know if this happens with other programms too, but i think its a Paint.net problem, because i see 2048 skins with better resolutions that mine.
I've got some new stuff for you. here i show you some pics of our new project, we are doing 5-10 different Race-Styled skins ( with the same base-design). The design is almost finisched, now i'm searching good logos.
Attached some pics
