Quite good considering its your first skin, the Audi livery suits the Pessima rather well. Only issues are that the left side sponsors are mirrored and the sponsors are copyrighted. Try making your own sponsors to replace the copyrighted ones or use those from the official skins.
The skin itself is great, unfortunatly you are going to have to remove it from the repository and post it on the forums since copyrighted stuff isn´t allowed on the repository. Keep up the good work though :)
