Alexa Hampton of Mark Hampton Inc. recommends 50/50 wall color and ceiling white paint mixed.....something to consider unless you love a white ceiling. I did my ceiling the same color as the trim although my crown molding was done in semi gloss and the ceiling was done in flat which is an easier paint job for a DIY like me.

I think the house is beautiful, restful, serene. I love the trees and would keep them. The brick looks fine. I'd paint the trim darker - gray, red, green - whatever, but keep it subtle.

The first thought that came to mind when you said "more contemporary" was black or deep green. Here are some inspirational photos. You didn't ask, but I would also remove the old schrubs and put in new landscaping. It would really move the home's look to the next level. Paint or replaced the front porch handrails your trim color and if you could replace them, select straight line ironwork. Add a new stainless mailbox and house numbers and change out your lighting. All these details will help you achieve the look you are aiming for. However, you can't totally change an "English bungalow" to a modern building without more structural changes, which I wouldn't do at this stage.

Here are a couple of ideas. Make all the front windows the same. Entry door seems really tall -- make the same height as the windows and add row of vertical brick above. I added sidelights as the door seems lonely. Make columns larger. Added full returns (circled in red on 2nd image) below gables with siding. If not, then a larger band of trim. I would not use a different siding on the dormer. You have chosen a mix of styles with a more formal brick and steeply pitched roof with short overhangs, but then adding the stained decorative truss and columns, and shakes on the dormer. I'll suggest not trying to mix in "craftsman" or farmhouse, and stay with the more traditional.
