Just a few sketches based on studies other (better) artists have done!
I find that this is a good way to diversify the way I approach drawing both with and without reference. Often I use pictures to get the proportion and pose correct, and then rely on my own ability to stylize it and add detail. ( Using lines where there in reality are none )
But this kind of studying lets me directly look at how other artists solve these problems, and try to adapt the ways they solve the various problems of angle and proportion. ( As well as how they draw various things! )
