Ok... Interlocking is not neccesarry for any map...period. I find it more than slightly irritating when the first post about a map is "needs intarlocking!!1!11!" It is somewhat recommended to smooth things out, or create good shapes, but is NOT always required.
Ok, mr. map creator, time for critisism. I see no weapons on the map, except for the aformentioned lazer (which ima firin'). A complete weapon list would be nice to tie your post together. Your bases are a little bland, they need to be slightly larger and more pazzazy (?). I like your middle structure in the way that it cuts the entire level in half due to its height, however, the lazer spawn will be a complete grenade spam fest which will take a little from the gameplay experience.

A forging tip for your future projects: Do not use 45's a.k.a. wedge larges, for they are too steep. Instead, ghost merge a wedge huge into the ground or use a ramp if you are not cramped for space. If you do not know how to ghost merge, I beleive
Forging 101 has a post somewhere on it.
Good luck on future maps and Donuts gives this a 3.5/5
