Lots of good advice from GW! For the map itself, you want to keep it basic. You don't need to show all that equipment on the map, just put a few chests & crates in the store room of the gondola and then you will tell the players what their characters find when they search. To make it more interesting some of the better stuff would be in a hidden / secret room or in a locked room so the characters have find them, negotiate locks and possible traps etc.
Same story with the monsters, they are not usually drawn on a battlemap because in the game you want to be able to move them around. You could draw in some random jungle creatures just to give the map a little more life.
Normal jungle creatures can be deadly enough, don't start with to many weird monsters, just a couple to let the players know that this is going to be different.
The map looks great with the gondola crashed on it.
