1st one: doesn't look like flunchers for me, and I doubt that can be considered cutoff.
2nd one: That's just missing the top part of the clouds
Also natnew, pretty good start. Levels feel a little empty sometimes but overall it's good for a new guy, and I can see you put an effort into it. Keep going!
I say remove the munchers anyway. You can't jump out, so you just fall to your death instead of waiting for the munchers to kill you. They look like flunchers because they "hover" a few pixels. It's your opinion on the ledges, but the cloud corners are a bit unappatising para mi.Your layout has been removed.
I don't really see a problem w/the clouds, but the muncher level was going to get an edit anyway, so it's changed.
