I like the colors on this Cape Cod house shown below. Your roof is close already. Could put new siding on over the brick I would think? Might want to beef up the roof overhangs just a bit on the dormers, making them a little more substantial? Could install a new door and add sidelights to the front door; don't think there's room for a top light like in sample below. Could paint the bay windows the yellowish color as shown?? Cut back the grass from the house in the front and add some landscaping (bushes, perennials, etc.) Good luck!

Sage green siding would be a good complement to your brick color.

Check out Romabio which is a mineral based paint that's great for brick. Painting this particular brick certainly would not be a travesty! I love this Cape Code with cream paint and a wooden door. https://www.thisoldhouse.com/curb-appeal/21277019/cape-cod-style-house-renovation If you haven't already, pin houses you like on Pinterest or make an ideabook here on Houzz to nail down your preferred style.
