Beautiful work, I like how all the tones play into one another- it feels iridescent, most predominantly in the horns but also in a subtler way along their fur.
Ack, I'm glad you like it! My color game is a lot stronger then what it used to be, and I'm happy I was able to create the effect well (It has only been a few years, but i used to refuse to color anything )
Sometimes we remain hung up on strange artistic choices, the one I've been learning to shed was where I'd insist on giving everything line art, it caused a great deal of image clutter haha. I'm glad your color skills have been increasing so quickly!
