Please post the original 1x images. We can zoom in (by clicking) but not out.
Also your resizing technique is wrong (at least for the tree), messes with pixel crispness and color count.
If you do resize pixel art, you must use nearest-neighbor resampling / integer factor only (x2, x3, etc)

The tree pixeling looks a bit random, you have used the same texture everywhere.

The rotating cup has a perspective problem: it's seen a bit from above but the handle rotates as seen on a level. What about pixeling the beans too?

thanks for the tips! (thats what she said...)
seriously, i did not notice the perspective thing on the mug until after your post,
thanks for pointing that out!
also, i guess i enlarged the pictures a bit too much, i reckon enlarging them 2x might let it remain small, but big enough so the pixels are notices.

for the tree, initially i wanted to keep the pallet simple, but then i changed my mind halfway and its like a train wreck kinda...

thanks for the tips and the reply!
