Fog - yes, those are VERY dark (overmelanised). Some of the darkest I've seen.
Geebsie/VC - note his black saddle feathers. Light eyes, would seem that they should be dark being overmelanised, but he's not. Hmm....what do we think? Ear coverts are dark, too. I see the items, but I'm frustrated, as I don't know what they all mean TOGETHER.
Fog - so, this boy has an excellent angle of tail; his back is of good length, but he's too uphill. It apears he's holding his wings at angle (they should be held horizontally) but I don't think that's a big deal. He looks like he's a good size - appears to have a nice, broad chest. I'm NOT an expert by any stretch, though!
If he were mine, I would put him with girls that are mossy. Perhaps that cross would = a more well balanced color?
