I'm just posting to generate some interest for the project I guess.
No offense, but this is definitely not the place to do that. Forgive me if I'm mistaken mods, but if you are posting here, the purpose is entirely to receive feedback of the artwork in itself and improve as an artist.
There's a lot of strange things happening perspective-wise in the new background. Those stairs should not be changing in width due to perspective since they mostly should be on the same plane (? not sure how to phrase that but it doesn't look correct to me.)
The crack in the bridge looks rather sloppy and as if you simply erased a bit and didn't bother to define any forms. Rather than color-filling everything to define objects, use some of the other colors you have going on to build and sculpt forms and shapes.
The HUD needs to stand out more from the background- I'd suggest a white outline.
