Well Im sure you lot wont mind if I post the pic here.
Thats a very nice pair you have.I really like the overall Dark look and the colour schemes work well.The skin on both are fantastic though the clothing on the girl could do with some detail picking out and extra highlights on the dress,without making it too bright of course and spoiling the look.
The guy is pretty much the same.Nice metalics,though if you brightened up the exhuast vents/chimney stacks on his back you would be able to paint on some nifty soot effects.As with the girl his clothing could use an extra highlight to make it pop more.
Sounds like Im nitpicking but as Ive scored it 9 I reckon you wont mind.
