Thank you very much, it's very helpful :)
I'll look into some more anatomy books, and go over ones i have, It's probably about time.

Before proceeding with any edits you may wish to study the following - scribbling by pencil along with reading:

It is from Drawing The Head And Figure by Jack Hamm, old (1963) but interesting book. It was reprinted several times, so you can easily find scans online and there are some chances that your local used books store has one of the editions if you want hardcopy (don't know if it was reprinted recently). Also Famous Artists Course scans are worth searching.

Ahh it's so true, thank you for the comments! I didn't even realise those things myself, I might have to do a bit of editting soon(if i'm feeling particularly un-lazy :)) Cheers for the welcome!

This one is great! But it would win if chin was fixed - she looks straight on viewer, so it should be on the left as on the right. Similar thing about shoulders - her left has curve as it holds something with big weight.  On paper such things are not obvious, but in pixelart all minor mistakes are clearly visible.

Welcome to PixelJoint, by the way!
