Very good, especially if you're not a fan of the show! I like how it's quite simple but really lovely - and has the "Moulin Rouge"-feeling, indeed. Also, drawing Repton isn't the easiest thing on the Earth, so I can't say anything but one: love it! Keep drawing!
I'm planning on writing a fic where Repton and Starling attend the victory ball on Terra Rex after the fall of Cyclonia (Repton doesn't particularly want to be there) and Repton finds out that Starling reciprocates his feelings.
They showed us the Gothic Tower scene from Moulin Rouge in my Film Production theory class at uni and I immediately went "that's the dress that Starling will be wearing at the ball!"
I briefly mentioned the ball in another R/S fic I wrote last year, I have two fics involving them them up on ff.net and they're both pretty angsty, I guess I must like seeing my favourite pairings suffer, Stork and Piper will have some angst as well if I ever get around to writing for them.
