Nice fish.
The difference in the perceived quality of the shiro between the two koi (that some have mentioned) could easily be accounted for by the difference in the lighting between the two pix. Remember: We're looking at pix, here, not fish.
As for the cream head on #2, that's not a problem for me.
I'd take koi #2 over koi #1 based on better bone structure and what I feel will be a more dramatic presentation when it matures.
Of course, with showa like these who really knows what's going to happen?
