Hey, cool looking map! I like the textures and the 3d skybox rotating dude :D Few things need to be sorted though; Firstly upon surfing the first two ramps I got stuck, so you need to aline and fix them. Secondly your particles are named correctly and thus can't be used on servers such as Mapeadores which has restrictions on maps which use particles, I suggest you change the particle names to custom_particle_001, custom_particle_002 etcetc, if you're wondering why, click this link and it will tell you everything; https://rafuron.wordpress.com/2015/03/04/how-can-mappers-help-to-prevent-the-infamous-particle-crash/
Once again, really awesome map but it would be even better if you fixed the surfs, might as well check all surf ramps to make sure, and then change particle names :) Looking forward to it!
