I dont know in regards to your question, but that is a super cute style!
The two things I think of though is that...
a: it draws your eyes across the hairline to the knot at the side so your eyes do not fixate on the hairline itself. Possibly a good thing. Especially with light skin and hair which softens the contrast.
B: the sides are pulled back so expose the angle of the jaw (where your jaw sharply turns up) which many mtf cover initially as it can be a masculine area (ffs often shave bone here). Some girls are lucky in this area and just have a brooke shields/ange jolie tjing going on... others are more robert redford/brad pitt and hide this with long bangs.
C: you should note that the forehead of this girl is small- and this style frames it nicely. A short brow to hairline distance is a very feminine feature... (though again see mz Jolie or summer glau for examples of larger foreheads that work) again FFS often brings hairline forward for this reason.
D: braids are feminine... it will clearly help people gender you. Thats a pro... it may be a stronger signal then the hairline.
I think its definitely worth experimenting with!
