anotomically, its questionable. It's assumed your trying to achieve that, yes? Its looking better, but it seems you tweak something and something else moves out; which if it was drawing would mean you are moving something too much and it should be just a tiny movement of line or shade (usually) that sort of puts things right..? Your changes are too drastic maybe, go back to how you feel most comfortable and make minute changes at a time but know when to stop. but anyway,go with the most experianced, not me, of course you have seen some of the WIP lately, your in luck at the moment mate.
keep fighting on
I'm also as curious see your image planes
take it easy and life will be easy
