I've begun with a full-body 'how-I-sketch'-thing but I realized that that wouldn't help you very much, because I already am used to the anatomy.And I know already how to draw the body-parts
you can find many other tutorials about 'how to sketch', you only have to use forms, lines and circles... and you have to know where to place them
and I can't really explain how to draw hindlegs, there are so many ways of drawing them. you have to find your own way of drawing them
so I thought this is a better way to show you how I draw
But don't forget, this is my way to draw, there are so many small details that you can change to make it look totally different.
A good way to learn: try to understand the body you want to draw. You can either study photographs of them, or drawings. How to 'study'? -copying. yes I know, copying someones drawings is equal to ''stealing'' but I mean like, try to trace the pose and try to understand how and why it is drawn like that.
I for example have watched many drawings, and mixed the art-styles I liked the best and created my own style/way of drawing
I'm not sure if the skeleton is 100% right, I'm guessing a bit at some parts
Hope I could help :I
