This, to me, harkens back to your 'old style', before you made the 'refined-cutesy' turn, which isn't bad; that's what sells your designs.
I like this return-to-form for you, and I wouldn't mind seeing more 'serious' designs like this one.
Good luck!
haha@go easy on me...I think you can handle the criticism :p
Always sweet to see you embrace your more abstract side like you used to frequently do, this is definitely one of your better experiments both in character and color.
