as I do not know how to use advanced drawing programs I do everything for Paint that is one of the ones I did in a short time I will not colorize because Paint is too bad to use colors

Taking in consideration that you did it on paint that's actually very good. Anatomy is great, I suppose you already have experience with traditional methods, am I right?

Did you use a mouse or a tablet?

I use the mouse that makes difficult more well-made traits. I make many face designs and the beginning of the shoulders I have trained muscles and hands
