Hi I have a lot of experience in creating video game assets.
I'm mostly used to CryEngine and UDK, but I can make assets for Unity as well.
I can make lowpoly objects with normal, diffuse, and specular maps.
All I'll need from you is concept art, or a general idea of what I need to make. Then I can make a lowpoly and highpoly objects to show you my progress in the task.
