Your nose is gorgeous to me! You absolutely don't need to get any work done.
Unfortunately, that is easy to say but I know all too well how hard it is to accept, and you aren't alone in these feelings. Countless women and even men, regardless of being trans or cis, feel pressure to live up to standards of beauty that are set by the media. And frankly, a lot of the times I don't even think those standards are that beautiful to begin with. Often it isn't even that the individuals in the media find that standard beautiful themselves, but rather it is all about what they can sell.
Surgeries to pass aside (which is a different issue really, at least to me), I've always believed that authenticity is infinitely more attractive. You mentioned the Barbie doll look, and that sums it up in a nutshell.
I'm also guilty of these same feelings about myself despite the view I hold towards others. I have no idea what will or will not eventually help me pass at the point I am at, but in the back of my mind I've already somewhat resigned myself to nose work. I feel it's bent and out of shape (though I do honestly believe I have a deviated septum from a childhood injury), and no matter what people tell me about it looking perfectly fine, all I can see when I look at it is that slight crook and little spur inside one nostril. Trying not to hold yourself to an unfair standard is a really hard thing to do when you spend most of your life hyper analyzing everything about yourself you don't like due to issues like being transgender. :-/
