So, you haven't been at life drawing at a while and you need to keep the old skills up?
Here is what i do, i use netflix and draw-but there is a catch-if you are interested at all in it, if it has production values or an interesting plot-Just Say NO!!
Pick something you have no interest in at all-turn that sound right down. You don't want any errant dialogue catching your attention.
Then draw, draw draw.
And thats how i came to watch the scorpion king 3
