Hi there. I took a good look at the pics you posted, and a few things come immediately to mind. First off, you may well want to get a concealer of some kind, like Dermablend. Your beard does show a bit, even though you have to look hard to see it. Your upper lip has a classic male shape to it, brought about by your facial shape, and accentuated by your jaw. Your lips just aren't all that petite. If you look at the full picture of you, rather than the close ups, that wig is giving you away right off the bat. It's the shape of it on top. It's very round and poofy up there, but stops at the bottom of your ears, and thus draws attention to that area of your face - which is your jaw line. A softer shape, with longer tresses that go past that part of your head may draw the attention away from your jaw. I also agree that bangs all the way across your forehead would help a bit.
So it looks like your next outing might be a fun one.....wig shopping!
