Every so often, I try to direct you to accomplished artists who have You Tube channels, websites, etc, which I've found to be helpful in my journey to improve in my craft as an artist.
An amazing artist I've recently discovered is SYCRA YASIN. He has tons of helpful tutorials which I've been watching every chance I get. He teaches practical ways of tackling difficult drawing obstacles, such as foreshortening, drawing dynamic poses, anatomy, and more!
Check out his YOU TUBE CHANNEL
I so appreciate the hard work he puts into his videos. This is like attending a terrific art school for free, guys!
