I like your thumbnail sketches - a good step. In the final sketch I would make his left fingers variate more in length. Make the total of him a bit smaller and place him a bit lower. Add some space to the left of your comp to give Ez more space. Those are my suggestions ^^
Great sketch! Really fits the league style. One thing that bothered me at first is the intersection of the railing and his hand, I thought it was a weapon he was holding. I love having the diagonal though, just something to keep in mind. Good luck!
