It's a perfectly healthy looking girl. She is not going to grow much anymore, females are smaller. You might want to add multivitamin powder 2-3 times a months or so.

Do you see how small in comparison to a body her head is ( first pic) and narrow too? Males have way wider, massive head. The last pic ( eye level) confirms that the head is pretty narrow, giving much cuter look. The fact, that she is eating great, proper and supplemented food, looks healthy and at 1y old is 4.5", confirms that too. Middle stripe that she still has is typical for a females too.

Beautiful frog!
