Deco doesn't match the goal.
Deco doesn't really represent city theme and looks more like a disco ball room.
3d on both perspectives of gravity.
At 00:11 there is 3d on both up and down which doesn't make sense given the perspective of the player in regular gravity.
The portals and orbs have color despite being "monochrome" theme level.
First id replace the block design to something a little more complex and city oriented that fits the themeing and using glow with blending try and light up the blocks more to give them more of an alive city feeling.
Next id redeco the upside down 3d parts to look like they are from the correct perspective using the new blocks and then id turn the brightness to 0 on all portals and orbs and use other blocks like hexagons or stars to make them easier to read while keeping the monochrome coloring
The block design and perspective issues overlap and can both be solved at the same time by just doing the block design and replacing the old one.
