Snark, I hope you donít mind, but I pasted them side by side, because I too kept scrolling up and down to compare.
Your shading is awesomeÖ and I didnít see anything wrong with it until I read others posts and I tried to look deeper at what it is you wanted. I can see now that it is a pretty drawing more then the moody aspect that is evoked in the photograph.
My arty friend said to me once a long time ago, that a drawing isnít ever ruined, because you can keep adding to it to cover up your mistake or until you get it right. Ack I canít remember how she said it, but it rang pretty true for me.
