Experimental Loki piece

Basically, i'm still new to digital art, and i want to start practicing properly, but it's kind of hard on the free software I have. After looking at a tutorial ( [link] ) I found something called the Ink tool, and here i had a play around with it. but then i started adding proper shading and it wasn't just lines anymore. But i like it. I didn't really use a reference image, but I was influenced by this image : [link]
*THIS IS FAN ART I DON'T OWN THE CHARACTER*
