What would be the best way to model bushes? They need to be realistic, but not too render heavy. What would be the best way to do that? (besides using pictures)

Actually I would like some pointers on this as well. I have a general knowledge of how to do so and could probably do it, but tips would be nice.

My approach would be to use Arbora or the Sapling addon, but then this might already be to render heavy for your purposes. Maybe you could find an easy way to reduce the load by tweaking the leaves somehow.
Or create a bush in the winter season :slight_smile:
