ABBA...eat your hearts out!
The glow around the floor dividers is excellently done! As a veteran of the disco era, I can remember people'feet being 'flared' all the time. The expression of joy on jessica's face is one of sheer exuberiance...nice touch, there; though I do question the 'pinkishness' of Her teeth. The musculater build-up on Her arms is ver well difined....really nice! And the fact that Her hair is lots darker due to the lower levels of light was well thought out, too.
IMOHO. the only way to make this any better would have been to add one or two people in the background. But, that might have distracted from the focus on Jessica. I'm guessing that's why you did it that way.
Nice job: well worth the '9' I gave it. Have one on me:
( after 14 attempts, I finally got this to post. SHEESH! )
