Finally played some levels :)
Bashing through the Snow - I think I got this one intended. If so it's a very nice, well-hidden solution. I especially liked the idea of getting a second worker lemming separated from the crowd by using the stacker.
Enjoy Yourself - A very nice looking level! It seems that there are many ways to complete this level but none of them are obvious.
Out of the Frying Pan - I managed to save a blocker on this one so not sure if it's intended. Still a well-crafted and looking level. I liked the idea of the "cages" in the level design.
Why Worry? - This one I know for sure I backrouted :( The intended solution to this one looks like it's the hardest of what I have played so far to find.
Thanks Nessy! :)
About your solutions:
Bashing through the Snow: not intended, but a very good solution. I think my solution is easier than yours once you think of the trick I use for it.
Out of the Frying Pan: not completely intended, but a very good solution. This time I think my solution is a bit harder than yours. (The glider!) I might change the distance between cage 2 and the chain of cage 3 a bit so that platforming there like you did is no longer possible.
Enjoy Yourself: well done again. Like you said it's one of the many (not too easy) solutions.
Why Worry?: backroute. I have to tweak things again and maybe start by putting some steel above the exit. ;)
Edit: New version of Why Worry?:
