Not a furry, but I love your artistic choices and like the paint style! Kudos for going with strong colour. Brave choice.
4/5 because we're all improving :). I see what you intend, and it's really interesting.
How did you achieve the fur? Did you stroke each line, or use a texture brush?
Only critique is the cyan outlines on nails & spikes. I don't know this style, but I feel like a different colour of line would have helped. Perhaps I'm wrong? But I tried a quick re-colour using the purples/blues of your background and it "felt better" somehow. Maybe this is not what you intend, just offering.
Anyway -- you're reaching a non-furry -- that's impressive :). Good job!
