I was temped to give you a 2 here, but since the map works properly I feel I cannot do that. Just as on the first file you uploaded, all you basically did was swapping the textures in half a dozen places. Proudly listing yourself as "author" at the beginning of the script is still the biggest change you introduced!
The map doesn't look even remotely like a jungle - a jungle needs trees, many, many trees! Besides, the script contains some bugs. Try starting it with the debugger; you'll see that you assigned an illegal map type (amazon)
at one point.
Who needs a new map that plays exactly like an existing one? If you look at the two "Winter" maps available here, one was meant to go with a tutorial, and the other one at least changed the gameplay of the map in question. Try to go for something a little more original next time.
