My name is Lenin. I attend a 2hr life drawing session every Sunday. On the rest of the days I practice - quick sketches/ gesture drawing, contour drawing, drawing the mannequin etc for about 30mins.
I am a big fan of Line drawing and that is my priority at this stage. I don't know much about shading, coloring etc. but I would love to try them out when I'm getting bored.
So, looking forward to suggestions on how to improve.
With subtlety(is that spelled right xD?) I just mean that you could maybe try to press lighter on some parts of the lines to imply light and then, as I wrote, make the line opposite from that, darker. Its not a huge deal, I just noticed that your lines a quite harsh : ) maybe what it is, is that you try to get the right line in the first try? so you stress about it?
I should have written this in the initial response. I'm sorry - I even had to go look at your drawings again to figure out what a-month-ago-me meant : )
