Looks great. The thing I noticed right off is how detailed the grass and potted plants are compared to the rest of the background. While a little extra detail on focal points can be good this sticks out a bit, especially with the walls which are a simplified cartoon style and lacking any great detail.
Love the style, lower the more realistic grass to a cartoon level or raise the rest of the pictureto the detail of the grass and I would say it is professional quality. Everything else is just personal preference.
