Looks much much better with the increased brightness.
Most of the things that need fixing are just misaligned textures.
Top barrels' textures need fixing.
Probably should rotate the slope's texture.
Alas! The pain of having perfectly aligned textures on a tilted box. Nice try.
Derp.
I didn't check both bases for the above misaligned textures, so you should double check them.

Suggestions:
You definitely should add a clip brush here, as players can get stuck quite easily on the slanted support column and/or the wall corner if they're going at top speed.
This corner looks kind of awkward, as nothing's actually attached to each other or to the floor.
I'm not sure if you intended this, but players can hop onto the glowing strip and walk across to the bridge on the right side of the screen.
Overall in terms of aesthetics, nice job. The flowing water in the fountain also looks much more natural. I have no idea how the gameplay is though.
