Ooh, tough one. Eyes open is better than eyes 
closed, but centered is better than hanging off 
the cel. It would be difficult to make a judgment 
call without seeing the images themselves.

But rather than trying to sell the one worth 
more, or keep the one worth more, you might want 
to just keep the one *you* personally like 
better, regardless of whether or not it fits the 
conventional ideal of what's good. :o)
