Oh it's so much better berk!  Great improvements, and welcome to PJ!!! 

@AdamPlays
Thank you for your advices.
1) I changed the animation from 4 frames to 13~frames. I never had a snow globe so it was hard to emulate the motion :P Still crappy but better now.
2&3) I discarded the ligth effect on brown parts, corrected a little at glass part. Also used colors are 8 now, instead of 12.
4) It is a lean-to as littlesapphire mentioned. I played with it too. I hope it is more clear now.

@littlesapphire Thanks for your comment :D

Nice of you people to help me learn something new.

A lean-to, right?  That's what the brown thing is :3  Really cute, but I agree with AP; needs a little work, but it would make it really great.

Cute idea.  I have some minor suggestions.

1) The animated path of the white pixels look like they are gnats rather than swirling/falling snowflakes.

2)The dark brown and the light brown in the corners are awkward.  How does the light source hit the bottom of the globe - and only on that part? 

3) Similarly - the dark blue on the left side of the globe doesn't really do much.  The lighting in the globe would have a much different effect. Take a look at these nonpixel examples to see what I mean. 

4) Also it is unclear what the brown thing in the globe is.  A house?  A picnic table?
