First Unreal Tournament Map!

I'm currently playing a lot of Unreal Tournament '99, and since it is a rather simple game visually speaking I decided to give the Editor a spin. A few tutorials later and I now know a few basics that I could use to build my first map, which I did after a lot of trial and error (figuring out how teleporters work nearly gave me a headache due to a lack in easy to follow documentation). It's a very simple one, more of a playable testing ground than anything else, the scaling is off (map is to big in certain places) and I'm trying to kinda fix it as good as I can. You can actually notice the scaling problems, notice the height of the door on the bridge (which is the correct height) and compare that to the door at the bottom of the room (which is just way to high), I'll have to fix that later on, right now I'm re-scaling parts of the Hallways, it's a step by step process, but I'll eventually have gone over most of the map. This map is slowly evolving into something and I'm fixing it's issues one at a time, there are a few that I cannot fix however, lack of knowledge being the reason (though maybe I'll be able to fix those in a few months/years).
I'm not aiming for perfection or excellence with this map, it's probably really bad (especially in it's current state) but when it's done I hope it's at least decent enough for a game of 2-on-2 or 1-on-1.
Not sure if I'll release it once it's finished (if that ever happens), but who knows.
I tried importing a custom texture yesterday without success even though I followed the instructions of several tutorials, seems like I'm stuck with the textures that UT has built in, which is kinda sad, I just wanted to hang a little gag sign on the wall to give it at least a little bit of uniqueness.
If you guys are interested I can make more screenshots to give you a better look at it, just let me know.
