The most difficult part of this drawing was to find some kryptonite ropes... I wanted to post this pic in straight b&w lines but it was too confused, so I added two tones of grey. A simple pose ok, but what's the problem with simple things ?
What you have succeeded in doing, compositionally, is to give SG's body the same "S" shape as her logo. The grey-and-white contrast works well, too. Makes the picture more interesting. She doesn't look like so much like Superman's Kryptonian cousin now, but graceful and feminine, eros in repose.
