Helm I have a comment about the inking but I want to preface it with a little disclaimer. I come at things very much from an animator's perspective so when I ink, I think economy, the minimum amount of lines necessary to communicate an idea, etc. Obviously that's not your style but I wouldn't expect you to change it. But I think there is one thing you could take from the animator's mindset... it's hard to explain so I made a visual.
Your picture has these beautiful sexy lines that I traced in blue. You obviously planned it this way in your pencils and put a lot of thought into them. But then the way you inked them, they became kind of lumpy and lost in the details. I would suggest making these lines read bold and smooth instead of camouflaging them, since they are clearly the foundation of the whole picture. I'd have all your details play *around* those lines and make them the main feature instead of hiding them.
