Now you're shooting porcupines? ;-)
I think your darker background tones are more pleasing than the lighter ones that I seem to remember you using before. I'm probably mistaken about the earlier ones - my memory isn't what it used to be, not that I think I remember the memory as being particularly good in the first place when it was young. But as it is, the background works very nicely with the skins.
I have a problem about the guy: isn't he missing something, what with gravity and all...?
