I think the bottom section works best here- the top mockup looks noisy and the middle mockup looks disjointed, but the bottom one is a good style with the characters and everything.
I actually like the colours and the mood/atmosphere they create. The only gripe I have is with the chest, which could stand out a bit.
This is a really good looking game.
I like the world map out side most of all; the ground and castle entrances especially.
