Yes, your face will change a bit on HRT, but I believe just six weeks is not enough to get big changes. Actually, HRT will do very little about facial features, because they are more related to your bone structure, the shape of your nose, jaw, brow, etc.
It will definately round your face a bit (this change may take more time), give your eyes a more open feminine looking and your skin will get less oily, softer and whiter.
I think the strange looks may be more related to the eyebrow plucking (I'm assuming you are still passing as a man, because it is really ununsual to see a man caring about eyebrows!) I believe that two main things can give your face a very feminine looking: long feminine hair and thin arched eyebrows!
