the use of dynamic lighting and scripts was very neat, i liked the ceiling light effects and the nukage fog looked really good

the idea of having a big hydroponics growing area in a moon base is very nice, and is not what you see in pretty much any other doom wad. the area with the loads of 3D walkways in that "greenroom" was really well made and cool, made me think of the hydroponics area in Dead space.
from the screens i thought "this dosnt look like e2m4 at all" but you managed to keep the layout very much like the original, which is always good with remakes.
well, you could ofcourse work on some texture alignment, having less cutoff bricks and other stuff. theres also some texturing i didnt like, like the use of SILVER1(or whatever that texture is called) was used quite alot and in places i didnt think it fit that good.
but otherwise. GJ, i DEFINITLY want to see more projects by you, as this definitly goes up top on my list of best GZDoom wads.
PS. gotta agree with zap about AVGN
