I do think that you should continue with the project. However there are some problems that I see.
Firstly, you need to pack the textures you used into the map or else everyone will see purple and black boxes everywhere.
Secondly, you should make sure to disable fall damage and remove weapons from the player. I have a template file that I could send you if you like, it will do all of what you need.
On to the surf, I like the beginning, all up to the spin. I don't like the spin, its too intense too soon; everything before it is calm but once you get to the spin you have no time to think. The rest of the map feels too close together because of the speed you get from the spin. I think you should spread things out a little more or reduce the overall speed at that point to give people time to think about what is happening. My suggestion is to change the spin to just a 180 turn without any strafes. You could then move the rest of the map up thus reducing speed into the next part. I think would fit the style better as well.
Here is the template I was talking about
