Green Meadow Zone
Though I'll forgive you because of the one small screenshot, you're probably going to have to make it less cramped. I do like that you got a water FOF going, and the textures are pretty original.
Graveyard Jungle Zone
I wouldn't call this a "jungle" because all you did was make the wall texture the wood texture. Add some trees using a ceiling, and some tree trunks.
Goosebump Mountain Zone
I'll give you props for using a very original name. I like it! The only complaint (so far) is the seaweed decorations in the background. They don't fit with the snow theme.
Techno Eggbase Zone
The Void Zone textures are nice, but repetitive. Add some machinery or something.
Egg Hill Zone
wat
What is this horrible amalgam of random textures and flats doing here? There's hedge textures on a blue machine, lava mixing with acid, that seizure-inducing ERZ texture! I know you were trying to make it look less like THZ and more like a different tainted landscape, but...wow.
