And now for some constructive criticism:
Carottus has foreground and background tiles, like the huge carrot. Use a few other layers; It wil make the level more vivid and adds depth.
Adding some "vegetables" to the ground in layer 4 makes the ground look more interesting, though it hinders the player when he/she tries to run around. The vine plants with the pumpkins are very handy if you want to give areas more atmosphere; use those!
Using the moth event is an option too, though I don't know if it'll be noticed.
Try to set the backgound colour to something like dark-blue. White isn't realistic at night, unless someone is throwing nukes around...

I guess this is just a level at it's beginning stages...
