Water,Light and model placement needs more work. Also the pipe that blocks ur path after u get out from the green room, don't introduce path blocking if its not there in the original work. All in all its a very good port.

There is no reason to keep the original low res textures from 1.6, you can make this map an absolute beauty.

Also add greenery to the water, like water lotuses or something else to not make the water look so loneley. Some jumps can be replaced by models or other architecture while keeping the original units there, ropes can also be replaced for something better. If u want more advice contact me and we can go into a more deep dive. If this is the final release and u don't want to improve/update it then u can ignore all of the above.
