I really like the design with Ken and Ryu side by side. As Yotsuya stated, there are quite a few of the same characters in different areas. I think it would look great if you just had Ken and Ryu in the middle like that. Also, as other users have stated, I think it's a good idea to get your cp layout chosen, and overlay it on the artwork. Otherwise, I love the marquee, and I think the background you chose fits perfectly! Great looking stuff!
