Don't no if you call it flag one or two, but the flag nearest the cap spot, has a ramp going up the boxes, and the ramp is floating.
The ramp going down to cap could of been made alot nicer, instead of the top peice being kind of randomly placed there.
All your blue barrels have the wrong top texture.
IMO: You have to many in base paths, since your flags are rather close together and also close to the cap, you shouldn't have all those paths on the opposite side of them. The mid could use another path. Also some more filler would be nice. But for a first/second map it's good.
