That is NOT ugly. If your Mom thinks it is, show her some REALLY ugly coops. What's most important is keeping your chickens safe, healthy, and happy.
You could put a small window up front - just use a jig saw and cut a square hole - staple some hardware cloth and cover that with trim that you paint a different color (white or black) and then put a flower box under the window.
Or just hang up a planter hook and hang a flowering pot.
Great job and I hope your Mom likes the fresh eggs.
EDIT: I just went back and looked at pics again. You don't have room for a window to the right of the front door as I thought. So just hang a planter full of flowers. Where is your ventilation? Is there a window on the back side? If not, I think you need to add some ventilation.
