It is really nice for a playable terrain, a bit over average in my opinion, but I will give you some suggestions that I believe that are really going to improve it:
1. I can notice some overuse of grass tiles, you should spread some dirt tiles, they'll give a more natural feeling to it. Real life jungles don't have grass on floor, they have dirt and fallen leaves! [useful links >>

I learned that trick from Void, and it really helped!
2. The paved path is too linear, there should be even more destroyed spots, to make it look less correct, and add some wreckage feeling. [useful example >>

3. Some shrubs are too spread, they should be more clustered.
Well, that is only some tips I felt like giving to you, but the terrain is okay.
Keep terraining!
