I have been debating if I wanted to critique this rooster or not, mostly because of the time I knew I would put into thinking about this perty boy. I personally find buff the most difficult color to breed. It presents many challenges, the most common is the inconsistency of the buff tone throughout the bird. The red wing bar is something I avoid if possible. Black and White feathers in the tail are not terrible. It is worse if its in the neck and wings in my opinion, as well as the underfluff. The main color you want to avoid is white. Black can be worked with. Although your end goal is to produce consistent buff color throughout all parts of the bird, including right down the entire feather shaft.
I try not to judge body shape too much on youngsters. This boy appears very young (probably under 6 months). If I'm wrong on that, then I would likely have reservations on letting him grow out any further. Less than a year (and sometimes even 2 years) is too early in most cases to know how he will truly fill out - even his color. If he is your only possible rooster, you could certainly grow him out and try to match him to hens that offset his faults. Sometimes this will resolve your issues and sometimes it will produce new issues. The only way to know is to test him. If I had a choice between him and a much cleaner roo, he would be gone without a second thought.
As he matures more, I'd look for the back to appear short and wide across. The widening can take up to 2 years to fully fill in, but he should be thick (broad) through his back. He is looking a little long and perhaps a little slimmer than I'd like, but I am thinking that is his juvie age showing and possible that will look better as he fills in more. It would be interesting if you keep him to see how he changes as he matures more.
I always find buff the most interesting color to follow through maturity.
