This is exceptionally good! The shirt and that design - you are commended. I'm most impressed with your clean lines. It makes the hair and mouth/teeth just outstanding. Good skin and hair too. Brilliant!
took a long time, I draw the out line lightly to start with, once I was happy with this, I choose a 6b pencil and carefully filled the lines in. I also find it useful to do a extremely light grid to help keep the pattern as close as possible, as it is easy to get lost.
blending sticks are different sized pencil shaped paper items used to help blend, great for areas hard to get to with tissue, i.e. the eyes. the link below will show what they look like [link](ESTOMPES)%20ASSORTED-drawing-accessories.htm
