I've had a few fairly simple ideas for a while. They're kind not related at all, but I didn't want to make separate threads.
1. Choose your texture in the character creator. So I know you can make your own texture on presets, but I don't always want to use a preset. The canine texture is always for long hair but what if you want to make an character with sleeker fur like a doberman, greyhound, or other short-haired character. Same with the feline one, what if you want to make a snow-leopard or a Persian cat, you can use tufts but they are still not that realistic. I think you should be able to choose your fur texture, it would be an option in the character creator. They would have different types including long-haired, medium, sleek, hairless, and more. This would help allow you to make other non-wolf/lion canines and felines more realistic.
2. Auroras in the south pole. That's all to be said about this.
3. I know you can make mods, but that takes a while. This is just a simple suggestion, but make the night sky more realistic. Feral Heart is meant to take place in the wilderness but the night sky looks like what you would see in the city. Many more stars should be added, possibly arranged the way they are in real life. Maybe even add in the milky way, I think it would make the game more realistic and also enhance the feel of the game at night.
Here's some pics to give you the idea:

That's all for now. I may add more ideas to this thread later.
