I really like the colours you used and the concept is brilliant. I agree with what you said in your description - I'd rather use my imagination than have someone show me what it's supposed to look like, or show me what theirs looks like...like it's nice to see how someone else sees something but once you've seen it that way, you can't really imagine it another way (if that makes sense XD)
Anyway, I love this piece and I believe you definitely deserve the DD
Congratulations!
