Angel on Fire-Castiel Fanart+Speedpaint

"Oh no, a floating head!!"  
Well, yeah, this was kind of digital art practice. I thought since I had worked on some traditional art, I should work on my digital art as so I wouldn't get all rusty! Great news actually, I finally figured out how to properly use quick masks, and its all thanks to this digital painting  tutorial I found on Skillshare!!  Now maybe I can find one to help me with markers!  

So why did I draw Castiel of all characters, well, I haven't drawn him in quite some time now,and I just finished season 12 of Supernatural... and so yeah, I thought he would be a good test character for some digital painting. As for why he has two different colored eyes, well, guess you'll just have to watch season 12 or watch Supernatural in general to find this out, because I ain't spoiling nothin'!   
And sorry his hair's a bit lighter than he normally has it, I think it was because of the color I chose for the mask layer, it was very light, so I'll try a darker color next time!
