One of my favourite artists on YouTube and Patreon is Canadian painter Sinix. He has a wealth of videos available where he demonstrates digital painting, anatomy and more. I am constantly blown away by his work.
You can definitely tell when he draws and paints, that he possesses an intimate knowledge of anatomy and color, a result of years of solid study no doubt. He is an incredibly skilled artist and as a bonus, his voice sounds like he is always really happy, which makes it all the more enjoyable to watch and makes me smile!
I have linked a few of my favourite videos of his below, check it out! You can also support his videos on Patreon and get some pretty cool rewards.
