Thanks alot guys for your comments regarding my pixels.
bengoshia:
The pixel you edited seems to have too much details that makes it a little bit hard to find out exactly what it is. I love the shading that you did and how you colorized it. If I was to do the same it definitely will take me decades to be that good 
In my opinion it looks fine, and not to sound offensive, definitely better than yours. But don't worry. With some effort, you could reach that stage in a matter of a few years or even less, if you try hard enough.
With that, well, let's see what you need work on... (
This tutorial is something you want to look at to understand the terms.)
-Outlines, although faint and colored, are still visible.
-Banding. Not necessarily pillow-shading, as on all pieces save for the vial suggest a light-source coming to the right.
-Palette lacks contrast. Furthermore it's just a straight ramp from dark to light, no variation in hues.
There are probably more problems which aren't that apparent to me as per the moment, but until then here's a quick edit of your lollipop (which almost doesn't look like a lollipop).
Redid palette, added a highlight to suggest glossiness, made some of the stick visible inside the lollipop to suggest transparency. Since I've never actually seen lollipops like yours before, went with a sphere with a band in its midsection.
