all you did was model the box, add the rotooz, and add the decal, and pose the characters.
I thought it would be in the RoTooz style (like you modeled it like this:
Its original on roblox cause no one has made them yet. Doesn’t matter if they have the same concept, if it hasn’t been done on roblox its orignal in the community.
the concept is the entire thing. its not like you can split the concept and what you get in one community and say “hey because it hasn’t been made in roblox it’s original”.
Personally I think there’s a lot more you could add to the Box Art, as its just a logo and a small screenshot of the character.
As for the characters themselves, they’re alright, but if you wanted to go above and beyond maybe add your own meshes / use a toy or bloxikin look instead of just the default ROBLOX models.
