Are those clouds? If so, you probably shouldn't use pure grey -- perhaps a light blue hue akin to what you did with the distant clouds would work better?
I have a few nitpicks about the baddie blonde dudes I forgot to mention in my previous post. The first, most noticeable, one is that he looks like he's got huge monkey-lips. Only when you zoom in do you see the facial structure you were attempting, and only if you look hard. The way to fix this is to keep in mind the light source is coming from the top front (apparently) so that means that any important parts of the face should catch the light more than others (whether or not it's completely realistic), and in this case, the bottom lip should catch the light because, as it stands, it looks like his lips are recessed inside his mouth or that he has really large lips. If you still want the chin to catch some light, you can move its light down a pixel to chisel out both the bottom lip *and* the chin. You should be able to keep the light on the top lip as is though to give him that ape-like look he has now (which is kind of funny -- just minus the huge lip effect.)
The only other nitpick is that the toenail/big-toe on the outside foot of the blonde dude seems to be on the wrong side of the foot (he really does have 2 left feet.)
Other than that, I can't really crit the background since I'm not sure what you're going for with it -- atm it looks like a dessert, but you said this was a beach-bum game, so I dunno. Hope what I did point out helps you out a bit.
