For a first map, it seems to have done well. Regardless of whether it's good or not (it was fairly pleasant) it serves as a teaching metric for how to do things like lifts and mirrors and underlava things.
A few notes:
-The windows by the green armor are pass-through, when idiots like me play the map they can get stuck outside.
-The platforms across the lava are a
bit to far apart, I'd add more and make them in a not straight line, probably just my tastes though.
-There's a deep hole in the lava, either put more of them in to make it seem normal or put something in it, it looks secrety as it is.
-Wait that's it.
-I like the mirror.
-Yay ZDoom affects.
-Congratulations you didn't fail.
That might have helped, if you did it from memory it probably would have had more of your flair in it but eh.
