I have some hands on experiance with photoshop, so i can help with textures and whatever, not so good at mapping yet, but if u need help making things look more realistic or need me to make a sample so u can make it into a map, i would be happy to help.
i would also be happy to do some testing.
i also know how do do basic fredding, so if u need some help, i can put together a mission 4 u and then u could touch it up to your likeing...
i would be best in the 2d moddelign area working on textures and such but should you need some help elsewhere... let me know... i am happy to help...
