I really think that the original pic looks best. When you go green it turns it takes away the blushing that the original has where the snake hits the state. Also, that original pic would look sweet on a t-shirt.
On a side note, what I would do with the name is use the same font, then scale up the letters you want to be "capitalized" then scale the other down smaller. I have done it multiple times with designs and I think it really looks good. It may not look that well it your design, but its worth giving it a shot.
