Excusing the fact this is the world's worst photoshop job (seriously I know it's bad but I just wanted to toss something together to show my idea!), I totally think there needs to be some trees at least BEHIND the Castle, in between basically the Castle and the turrets so that it blocks out Fantasyland beyond and gives more of an impression of the Castle existing in a woodland setting-slash-defining it better. Giving it a sense of, I don't know,
scene? Something. It just needs....more. Like a background or backdrop to be framed against.
Placing them more off to the rear sides would prevent problems with Wishes sightlights from the front but still provide a setting. I feel like the Castle is just lost and floating out there now since there's no trees around it anymore. It's just out of place.
