Well it seems like you have a good idea of what you want and where you want it! I personally like to put bushes and trees alongside my path to kind of "frame" it but more bushes and trees definitely wouldn't hurt! I notice you have gracies, so you can buy the bushes from Leif. I think it's a challenge to do the gold theme since there aren't that many PWPs that color, except for the sphinx/pyramid. The more royal stuff is all fairytale, so pink and blue and I don't know if that's what you're going for. Maybe torches? If you want more of a manicured landscape the topiaries are nice to add. Sorry if thisn't more helpful LOL
