Rocky Top Test

Working on a concept for a shirt and this is the first part that I wanted to nail down. Will need to add Tennessee to it but feeling pretty decent about the direction. I'm not the best with shadows and highlights, so if anyone has any thoughts on how to go about that would be great.

Also trying to figure out how to add Tennessee. Whether it should be in the same type or a different one. Again if you have suggestions that would be great.
