First that hits on eye is the unnatural look of a jungle theme. This lines are just not natural.

Now about map problems from the picture:

1) Gas issue.
2) Low decoration.
3) Terran could sige tanks all over a players location and eat him from outside. The terran can even not go into his main and still win! Wow!
4) You could reduse the center horizontal line, i think it's too long, and helps terran a lot in center fights, not to mention that the terrain is all buildable.
5) It's not very balance that you hit the gas from one location, and can't hit it from the other. Mayby you should put in the middle of the air exp, so every location have the same chance, of taking over the air exp.

Overall:

Well sorry, but i don't like the map much, anyway i can make you some suggestions, to improve it, after you fix the problems i guess. Look at GMCS.

THis appears to be interesting. Ive been floating around this site anonyomously for awhile until I finally came out with a good map. I need to figure out how to get to the forusm ti get assistance in uploading and figuring out how to lock it up so others cant steal it :P.
Despite it being a jungle terrain, I dont think the theme tileset needs to match the theme. Its the idea behind a map that counts. Besides, in the end, its just a tileset. Theres no difference other than color and doodat sets :P

after deathman, kinabears came to bump old maps with dead authors

gz, you can stop it, it's useless.

honestly kinabear that was most useless comment I've seen on this site, and that's including "your comment" and "lol", not to mention you bumped a random 3 year old garbage map for no good reason.
