I'll have a go at it! I'm from the ASL conformation crowd, so I'm still new to other lines.
The first pic makes his whole head and muzzle look very short, and his front feet appear long with a tad more angle on the pasterns than I'd expect from a working dog. Back is a bit high in the second pic, but nice chest. The bottom of the ribcage doesn't extend as far back into the loin as I would expect... It'll be interesting to watch him grow! I'd love to see his head from the front.
Totally pulling it out of my butt, so take it worth its weight! :P
