You are welcome. Your first is you best and shows great skill. You do a good job showing the edges with shape, shadows, and contrast. Now select your next subject carefully. Make pelimanary scketches and the spend hours every day for at least six months improving the finale drawing. Make it your masterpiece to date. Work on no other piece of art at all the whole six months.Thankyou for the lovely comments DLeeG.
As for the outlining, you are very right in that The first image is my most recent, and I think I have improved on the outlining issue on there versus my earlier images - I hope anyway!
