Well, overall the map is great. Good use of older style textures and the detail work is good also. There are some things about this map that bug me and some traps that I have no idea if they work or not. So let's get to it.
Traps - Overall are good and simple traps. Nothing complicated just simple stuff (even though for some new mappers the timing you had on some traps will be difficult, for me it is not). I do, however, have questions about some traps. 1) The trap at the beginning after the first one (so second one xD ) the one that moves. Why did you not make that thing on the floor a block? What I mean is that you can just go right through it which doesn't make it that good in my eyes. 2) Does that TNT trap even work? Because I pressed the button and nothing happened. I thought maybe it would explode. 3) The trap on the third picture you have here on that down path. Does it do anything? Pressed the button and saw nothing. 4) The last surf part traps is too slow and most people will be able to evade it.
Other than that, the traps are good and well made. No dark parts on them so it shows you know your stuff.
Now other little stuff that bothered me.
1) (This isn't that much of a problem cuz it doesn't affect the gaming part) Like the thing on the second trap, those things that you have to jump over before the third picture (I hope you know what I mean), you can go through them (although it's only in godmode so hence the first sentence) 2) That manhole cover at the last picture. Could have made it the size of the actual hole and put a better texture on it xD 3) That last surf part. You can basically skip it whole and surf on that wall to the end. Pretty easy to do xD
Other than those things, everything is awesome. I have no idea how this is your first map, but I imagine you have done something before just not posted it here. Anyways, awesome work
