Her head seems too large for her body... maybe it is just the winter coat...but in the spring I would get her working to start building up some muscle. Time trotting in a round pen would do wonders. I am with everyone else, she looks to be a pleasure ,,, that is all I hope for in my horses as well!
My youngster has already been through that phase twice and he's only 13months and actually has a very dainty, 'pretty' head for a warmblood.
It is very hard to judge conformation as a youngster, particularly at this age. The best bet you will have is to look at them at 3 months old. Generally they will resemble this once they are mature. After 3 months, don't even look at them until they're 3 years as they go through so many interesting growth stages. Unless there is a glaringly obviously conformational trait, no one can tell you 'yes or no' on what she would be suited to.
I would just let her mature, break her when she is physically and mentally prepared to do so, and dabble in a bit of everything until you find where she really shines.
Unless she has been purpose bred for a certain discipline and you bought her for that discipline, then you're not really going to know what she'll be great at until you are on her back putting the training in.
