Looks good, however, 95$ is to much for assets. If you would also add, lets say, a blueprint fps script with 1-2 guns, i would say 95$ will be definitly okay because it would actually change something in the actual gameplay.
Beside the fact that in the community are not hundreds of lurkers who actually work on a steampunk setting, you won´t sell too much, because your assets are very very theme limited and i cant really remember that someone here is right now working on a steampunk setting.
Hope i dont sound to harsh, wish you good luck with your content and no matter what, guys like you fill and support the ue community!
