Thanks for the comments, the blue lines were originally more flame like but after seeing comments on other pieces I thought they would be rejected. I have a new idea for them and will try to get this updated tonight

GREAT work, the whole concept is just perfect! Congratulations for this GREAT piece! :)

I quite like what you've done with the shapes, though they could do with some AA.  The blue lines look rather ugly, though.  Try playing with the position of the highlight maybe?  I dunno.  I really love the contrast between the cool and warm colours, though.  Makes it really pop.
