Hi bro3dpro! Thank you very much!
I have some bits of my asset packs on Sketchfab already (https://sketchfab.com/PizzaDoggy/models), but I'll build some scenes from the modular stuff and upload them there soon too!
You can also check out the 'fish are people too' (https://kharibidus.itch.io/fish-are-people-too), it's a good example of how they look in-game!
And you can absolutely use the assets for stuff like trailers, screenshots, marketing art, devlogs, and streaming of the gameplay! There's no limitations on those!
