looks good, almost 100% sure it's male, which is not a bad thing with kawarimono, as they tend to still get very big and have good bodies still.
Pattern a little heavy on the front, but body looks good and long, and the scale reticulation also looks good.
The sora is also nice and light, and the cha a chocolatie brown which is my favourite on ochiba's
All in all I reckon this fish will turn out very nice
