i liked your second map better. but il be honest and say you got alot of work to do. heres my suggestions...

texturing; your texturing is mostly hidious, especially the liquids on walls and stuff. its best to stick with one texture set. complex achitecture: this skill is mostly learned only by making more and more levels, and observing other good maps for guidance, keep at it, dont give up. go to pfhorums and find, checklist for mapmakking by RyokoTK. there you will get all the real info you need.

i dont mean to be harsh, you just need to practice by making more maps (if you want to improve), but dont give up, we could really use more good mappers. i hope this helps...

also any advice that people give you in a rude tone, or try to chew you out. ignore their oppressing comments.. yet at the same time consider what they are saying...

I'm glad you got all the zipping and posting stuff figured out. I played through both maps for a minute or so, and thought up a few points of improvement:

1. Avoid dead ends like the tunnel in Tower. The map should flow, not require you to turn around when you hit a wall.

2. Avoid paper thin walls like the one in Upstairs

3. Learn to merge your individual maps into map packs, to make playing them easier. You should also name your levels in your level editor.

4. Upstairs could use some more cover. Aside from the paperthin wall, you are a little exposed. This is nice for some parts of the map, but even Thunderdome and Route 66 have quiet areas.

5. People will be more interested in your maps if your add screenshots.

I hope this review is helpful. Keep mapping and working on your technique.
