She looks a little tucked up, maybe to do with the cold and rain? But she looks to have a typical clyde back end. I always think a lot of white on legs sometimes gives a wrong impression. She's got a lot of developing to do - she looks a sweetie.
It's always difficult to pick a good two year old - I sometimes think it's better if they look wrong at that age as they will grow into a nice horse - a perfect looking two year old often means a horrible 4 yr old
I can see how some people may mistake the breed with the leg markings, but just look at the legs no way clyde or shire, for a two yr old she is very well grown, although I suspect she wont finish until about 7 or 8 so as she is also croup high has a lot of growing to do, she looks a bit short in the back, but thats makes for a good jumper, I would say she looks a bit light through the shoulder ( on the last pic ) compared to the backend, overall for a 2y old looks quite a usefull sort, I like her.
Agree with you, she looks cold and is therefore hunching up a bit, I think the colouring (white) on her back legs gives a bit of an optical illusion with regard to the hocks.
I think she looks good for a two year old and I like her lots.
