His biggest problem will likely be the post-leggedness.
He's not over at the knee. You might nitpick and say he's a bit too straight through the knee, but he's definitely not over at the knee.
People should not critique their youngsters. Too many important things change through growth that it's just wasted energy worrying about this or that.
For instance, as he widens through the chest...which surely he will do, his forearms will rotate around, rotating the knee and the lower leg such that he likely won't toe out. It's also possible...and currently looks like...his elbows are tight, which will also cause toeing out. If the elbows stay tight, they can be loosened through stretching and exercises.
I would like to see him trimmed a bit differently. Currently he stands 'on' the ground, instead of 'in' the ground, and it's making him quite upright and straight through the legs.
