Battle, by 
This level is a HUGE improvement over your last one! :D
Gameplay
It’s nice. You can move quickly through the level. There are just a few dead-ends, but most of them have a PU or a warp/suckertube out =) Too bad at 1.43 it’s a dead end. Maybe some ammo could have been placed there. At 32.17 it still makes you go in a vine and straight into a wall right after, but there are TWO carrots there :P It’s not a major thing. There’s not much to say. It’s just a good, solid level.
Eyecandy
Stil lacking, but this is improving a lot too :) In the bottom of the level, there is some background usage, but in the top there is hardly anything. Also, the bushes in the wall seem randomly placed, or just placed without any thought. But, I like the gem events you put in there :) I really like the waterfall at 74.21. Also, under some waterfalls, you placed Water blocks. You should try changing the ‘Y-Adjust’, so the splashes actually happen on the tiles, not in the air :P
Placement
Nice… they are in nice shapes, and there is enough for everyone. I think the PU’s are placed good and stuff. I would have liked more floating ammo instead of the two barrels 63.20 though. One thing I don’t like, is how the ammo is placed nicely, but the food is placed in huge blocks. Maybe do them just like food. The donuts in a row, maybe like donut-empty-donut or something like that. It would look nicer IMO.
Also, nice music you chose.
Bugs
The floating water blocks and just a dead-end.
General
It’s a good level and you are improving very fast. Just work more on eyecandy and try preventing dead ends or put stuff in them so it’s worth going there. The left side of the level still seems blocky, but anyway. Keep on going.

Maybe nice for Battle Server.
