i kinda feel like perspective is a little messed up with the deep one
it may just be me but it looks like deep was drawn from the different angle than bg - deep's axis stays vertical, but not bg's one

looks like you firstly drew deep without whole perspective concept and then you tried to put on long-hall-like background, which is off the perspective

Also his right arm (with sword) is kinda messed up. The hand looks too small.

edit: damn, I need to learn how to make it look round instead of being flat
