looks okay, but you probably should post your first couple maps, cuz for most people they end up not being of high standard :/
[spoiler]6/11[/spoiler]<-your score.
Excellent map for a first try!
Although the edges are a bit sharp and you get stuck and you could probably shade it aswell for a better effect. I also think im missing some textures or scenery that you used.
Wow...I like the lay out. The only thing I don't like is the color/shading of the polys...maybe go back and make the sure the three corners are more uniform in color? Do that, and your map will look a lot better. Any bouncy/jagged polys in there as well? Those could be bad.. 7/10.
About the texture I have some doubts, because when designing the lev, I used testicle.bmp I got when DLing a level and it didn't seemed to be in Soap's Texture Archive so I thought that it would be better to stick with the regular stuff to avoid problems :/
