Overall, I think you are doing a wonderful job with it. I agree about the big green tree, also would take out the large flowers at the back corner of the house and use a different grass fabric in the foreground, one not so tall and scraggly, maybe with variations of shades of green. That's me talking, who started a landscape probably 10 yrs. ago and it moved with me, but it doesn't move me, it is a mess, but I keep it. Maybe someday. Yours is so far, heads and shoulders above what I did, so my critique can be disregarded. Yours is really wonderful. Can't wait to see the final project.
