Aside from all else already mentioned, at least two things seem odd, but both could be attributable to perspective. The luff of the headsail seems to rise out of a stanchion on the starboard side, rather than the bow of the boat. The aft-most guy (standing up, gray shirt - we'll come back to him) appears to have an enormous wingspan. His right hand is on the boom, and his left hand is on the port lifeline.
I also see no one looking ahead except the foredeck guy (though it is a snapshot). I don't see a wheel, and I don't know this boat, but I can make out what may be a tiller. I hope it is lashed, because it appears otherwise unattended, which is odd in a race.
Back to the aft-most guy - he is wearing a very interesting pair of pants, left leg is shorts, right leg is "capri" length, and I can't find his right leg exiting that pant leg.
In addition, there is apparently someone standing in the companionway (always a good idea) in front of Mr. Grayshirt (right leg visible, bent at knee, and right elbow visible).
And finally, there is something not quite right about the sunlight and/or the shadows on the headsail.
Edit: The capri length pant leg may belong to Mr. Companionway, there is a detectable color difference in the two pairs of pants. But I still cannot find a right leg for Mr. Grayshirt. However, I now believe his left hand is holding the backstay.
