I see one spot that the box should be dropped. Anything that requires jumping to move from box-to-box is instantaneously bad. However, especially for a first map, I think it's pretty spiffy. I'll check it out and come back with comments.
ok the map design looks good but you should have made the interlocking a little more neat so when people are playing they don't hit bumps and have to jump to go up a ramp other then that the map looks great!
Good Job! Myfirst map was not even close to looking that good, heck I dont think any of my maps look that good!
