Nice! the main guy stands out much better now. Now I'd take a look at the cat and see You can make is stand out more too.
I tried to do a quick and ugly photoshop adjustment to see how you could approach it.
i lightened the houses and enlarged the cat a bit to frame him better an avoid some tangents
I really like the warm/cool diffence between the characters. maybe you could push that some more as well.
It is a great piece! I can't wait to see the final.
