Do feel the love in the air?

This is a great piece! I really like the hair flowing into the bottom of the picture from both characters. I also like the color choices made for this. They give a romantic, sensual vibe. I think the detail you've put into the hair is the co-star of the show along with the really nice details in the faces. Some really nice highlights in their eyes and on the noses (I especially like the character's face on the right).

One thing that immediately stands out to me is the collarbone of the the right character. It seems overly pronounced to my eye and is all one piece. The collarbone is actually two separate bones on each side of the chest plate. So it almost looks like a prosthetic of some kind. The left character's is also pronounced but in a way that makes it look like it could be a slight pronouncement due to her being a vampire or something. This may be the case for the right character too, but I feel like the bones still need to be separated.

Also, the left character's ear seems to be a bit too far back in the hair. At this angle, I believe that ear would be closer to the back of her head than where the jawbone meets the skull.

These being said, this is still a very successful piece I think! Nice smooth blending throughout with some really nice hair effects and highlights. I hope I am not being offensive! I just know I hate when someone says, "That nose doesn't look right." but then offers no reasons or specifics as to why or what could be changed. Great work overall!
