Bug and background look unrelated, both in concept (what's the story?) and design.
There seems to be a strong light source on the bug: what would that be in a winter landscape? Also the bug would cast a shadow on the ground.
Still too many colors! Obviously you create them as you go: not the best way. Check this tuto; 32 should be way enough here.
Not everything needs an outline. Colored outlines may bring contrast issues, such as the mouth / beak which isn't very readable because of low contrast, relatively to surrounding areas.
Check out for banding (another side effect of outlines; see "Things to avoid" in same tuto).
Want to give some dough back to all those amazing pixel artists? Donations provide prize money for contests, help cover hosting costs and support new initiatives.
I like this. I has issues though.
