A bit more rendered sketch, did it last night, about 3 hours. Started of using the double envelope technique, using horizontal and vertical lines to check proportion and position. Started to render the drawing and realized that the higher knee was way off and smaller, so had to re draw it again. After completing realized that the head ended up slightly smaller then on the model, but it still works. Overall happy with the result, very good study and practice. Drawing is A3 sixe, used 2B, 3B, mechanical 2B 0.5mm pencil & white pencil.
