It looks good but there are a few things that bug me.

It looks like you could make the MB compartment shorter so the case is a little more compact, but that might limit heatsink height. If you need the height maybe make the rear fan bigger since there is extra space, maybe even room for 2.

The PSU power plug is on the side of the case, which is odd.

Is the hole in the top a window or is that a spot for a giant fan?
