It's looking good. I would suggest extending the roof on the porch (over the door) back and putting a roof on the rest of the house. I would use a little more contrast in my colors, but it's ok how it is right now. Also, if your light is coming from the top right, then the highlights on the garage panels would be in the bottom and left side. The left of the overhang above the window shouldn't have as many highlights, if you make it darker, it will make it pop out more. For detail, I would detail the doors, put on shingles, and make the outside wall of your house have bricks or wood panels. You also need to put more shade where parts come out and you definitely need more contrast on the pillars.
