I don't know if I am the one who has the right to say this, because I'm an absolute layman when it comes to drawing, but from what i observe as a viewer and a fan - it is amazing how you increase your skills, how you're drawing style is evolving.
When I looked at this drawing, my jaw lioterally dropped. the effects, the lightening, ragged garment and... LOKI. Loki's just perfect. Loki in this particular drawing might be one of my ultimate favourite portrayals of Loki depicted in fanart.
Really? That makes me to so happy to hear. I get down about my art, pretty much all the time. XD I don't really see where I improve until I look back at some of my older work. Even then, all I can see are the flaws.. Tis just my brain I suppose.
