You've done a marvelous job so far, What a dashing figure he is!
As for the plants, they look like they could be roses on the wall and some sort of shrubs or trees in the background. With plants you can never go wrong with shades of green! A lighter shade for the rose leaves and maybe a soft pink for the blooms. The trees would be a darker green so they recede into the background as they should. It will give more depth to the photo. Make the wall and the house a tan with a wood window frame and the walkway I'd leave gray. Just my thoughts. You're doing great on your own!
