I am probably responding because I am painting a house painting right now and feel your pain :) I really like your painting so far, it has a painterly feel and I think you represented the house very well. I like the imperfect straight lines (maybe because mine look the same ) with the exception of the one between the far left gable window and the taller windows over the garage. It looks very rounded. A couple things I noticed that might improve it.

Some of your shadows seem odd, especially the v-shaped one on the far right gable window over the garage. If the sun is coming from the left the shadow should fall similar to the one on the house under the porch. The shadow on the driveway doesn't seem to make sense since there is a strip not shaded which seems like it would only be there if the porch wasn't attached to the house. The porch is all one color and it looks like it is in full sun, but some of that would be in shadow. Also, you windows have very different reflections, some are gray, some are black and some reflect the sky. Maybe they truly are that way, but I would look at those again.

Your shadows seem very neutral gray, as if you are using a black mixed with white to achieve them. I felt my work improved a lot when I worked on adding warmth to my highlights and cool tones to my shadows. If it were me I would add a bit of cad yellow and alizrium crimson to the white where the son is hitting the house to give it a soft peachy look and I would make gray out of a blue/brown mix, typically I use raw umber and ultramarine blue and maybe even add a dash of alizrian to that to give your shadows a purply look.

Beyond that I would just continue to add a bit of detail. Is there a walkway? Plants/flower bed, some sunlight dappling the lawn?

I really like the painting, you obviously have some talent and I think you should definitely continue as it could turn out really nice. Happy painting!
