I have a bad habit of working on a small section and exaggerating the detail that I see whilst drawing it, especially if the reference picture isn't that clear, this is a good example where I have overdone the lines on the leg and made it look odd.
I have also discovered smooth paper and improved my blending since this picture. I might have another go at it some time in the future and see if I can do a better job.
Thank you very much for your comment
