it will be tuesday after work when i do because i have a house guest tonight

Good job on setting up the poses on the bike and the background. I agree about the expressions, kind of... you really need to be careful with using slight and subtle amounts of expression. I think you did go just a little too far on the smiling girl on the left but not too far. I really think you were on to something of a Sugar and Spice kind of thing where the girl on the left has a shy embarrassed forced smile and the girl on the right is flirty and enjoying herself. It creates a nice character contrast between the two, creating a certain conceptual balance and making me think about the pic a little more... and that's a good thing. Nice job.

I would have to agree on the smile. It is almost Joker-esk and very unnatural. I too will offer what help I can.

well at least they are looking in the right direction. i'm not crazy about Raven's expression [looks like she's in pain to me] but that's secondary. the texture could still use a little improving. when u have some free time PM me and i'll walk you through some ways we can make this jump out a little more.
