Oh wow, color me surprised! To be honest, I didn't expect much from act 1 of paradise garden since it was so cramped and filled with crawlas but after that? You have something that you could really make into something impressive. Act 2 of Paradise Garden had multiple paths, was much more open, some better enemy placement and pretty good scenery. All in all, it's a pretty good zone but I feel there are a few things that you could do better.
I believe that some of your water falls in act 1 and 2 are incorrectly placed since they aren't in the sector that has the water but are instead placed over a normal land sector that has no water; I mean, this could be something you intended but usually waterfalls go into the water :P. I also encourage you to use less under water scenery things in such small areas, 3-5 are better than the 5+ you have cramped into some of the small little ponds you have in act 2.
I haven't gotten able to play through all of Warped Ravine yet but what I've seen so far, I like. Good texture use throughout the first act except maybe in a few places (ie the silver pipe texture that you use for some of the structures). The level is nice and open and most importantly: it's not short. I also found that I sometimes accidentally backtracked without realizing it because certain things flowed so well.
If you ask me, I think that this would make an excellent level pack to be added to submissions once it's finished. I think it's really cool that I can see how you learned new things about level design through each act and implemented them pretty well. Good job and keep working on this.
