I think this is one of the few shots where it looks as if basically just the camera was flipped that really works. It appears to be pretty well lit and the contrast is good -- it's just so pixelated -- not a lot of really good detail. Too much compression coming out of the camera? Without knowing the process you used to take it and do any editing, I don't know what suggestions I can make to hep.
I'm not sure what 'prawling' means but these guys are definitely upside down! A little extra shaprpness of focus on this photo would have been a nice improvement :)
