You should add a survival gamemode to this and atleast a multiplayer server so others can play with each other. If you do make it survival you should make it technical where you can make factories and drills because I think that would be a good idea since minecraft mods that are industrial get much more popular than the magical based ones and most games have magic and stuff but anyways cool game.
You should make a creeper apocalypse mod because i always see these 'i would survive so many days in a creeper apocalypse' so a mod like this would make the perfect test. It could be that conditions would be harsh so you could get burned in a desert or freeze in a tundra. Creeprs would come out during the day but less commonly than night when only creepers come out and kill everything in there path including poor piggies and cows. Also resources would be extra rare like in a very populated multiplayer server. If a player lives long enough so that any resources left are dwindled he can find ruins placed all over. I hope you like this idea and other people do too this would be absolutely awesome!
Could you make me shark that is green with red eyes and post it in my skin pack I promise I'll give you credit ill send a link when I'm done make the shirk have a white stomach too like a great white shark and the green a bright green
