There's one thing that bothers me so much and it would be a very simple fix. Make the feed zone indicators on the map for predators red with a little piece of meat!!!! It has always bothered me that the predatory species apparently eat.. leaves?! Changing it to what I've suggested would not only be a nice little visual, but also make it easier to see which feed zone you are looking for.
As always, suggestions to this post are always welcome, but I don't think there's more to say about this
