A very good quality model indeed. I tried to look the skate park all around and there were no artifacts anywhere. Skyline was also very clear in every direction. Thumbs up. Of course if you zoom in too much, there are no more details to be seen. But still no holes in flat surfaces or glowing objects from behind. Which is rare. If you go further from the skate park, obviously there is no more data either and less details. One of the best quality models anyway, although I like flowers more than huge concrete buildings.
I only think, how can you make such models more usable or more fun. So that models are not only an exact representation of the world but something more. Maybe something artistic. Brighter colors or cartoon like few sharp color palette. Only interesting method that I have found, is turning background grayscaled like here:

By that way the model size could also dramatically reduce. Have you check, how many gaussians you actually use for the skate park and how many to rest of the scene?
