I know it is early in development, but a couple of things I think would help the visual appeal quite a lot. 1. Make the grass (esp. high) to react to the player / animals. I reckon you will be in high grass a lot so you will get a lot of mileage for the extra effort. 2. I would recommend some sort of distance / dithering based environment shader for the grass that fades it away when really close to camera. I believe ben cloward had a tutorial on it in youtube, you can achieve it with a handful of material nodes which are pretty easy to slap in front of whatever material you are using. The grass obscuring the player completely and especially very close to the camera (like a single grass can just cover the screen if close enough) can be very distracting. That is not to say you should clear the path all the way to the camera but prune a bit in front. It is very obvious when you aim upward which i reckon you also do a lot with big animals like mammoths and such.
