Looks: 4/5. looks great for the first, more shading and more scenery would make it better
Gamewise: 4/5, all routes are on use, no bad spray problems except maybe top route. Map is very smooth. The minus comes from use of "only bullet collide" polygons which should be never used, makes gaming stypid. Solve the spray problem by curving of polygons instead of only bullet collide polys.
Originality: 0/5, superhyper basic design.
I see you have good mapping skills. It's future to show us if you got unique mapping ideas. This map is too basic that someone would remember it.
