Very WIP currently, just laying down some ideas for now. I am thinking of putting in a path, and will need to have something to catch the eye through the middle of the trees. I also need more trees/bushes to fill out the empty space. I plan to do more variation on the trees too (it’s currently the same tree re-coloured and re-positioned over and over).
You can set the particle drawing to only display a fraction of them in the viewport.
Another thing to not forget about is distributing the contents of the scene across several layers (which is especially important for scenes filed with plants and particle instances.
As for the image, the bright red coloring right now really grabs your attention at first, so I would try to reduce the density of the red elements a little so it won’t have a chance to drown out the surrounding parts (especially the statue, which you can barely notice because there’s very little light shining on it).
A final thing, the sky gives the suggestion the scene is sunny, yet the lighting assumes the scene is cloudy?
