I don't know if you're still looking for feedback, I'll put my two cents here as someone who always look for 2d assets :0
I would not use it as it is. Reason is when I want pixel art assets, I would usually get a complete package (e.g the floors variants, background layers, and then other objects like rocks, cactus, houses, etc...).
Cohesion is the main reason : If I pick one asset in your style and then put something from another source next to it, it might look off if your style is too distinct from others.
I think you should ask yourself some questions when it comes to giving people 2d assets :
- Which view are you delivering? (e.g Top Down, Side scrolling, or Isometric)
- Do you want the aesthetic to fit a pixel art style? If so, which one? (1bits monochrome, 8bit palettes or more complex ones (16-32bits, etc...)
- If not, make sure your assets have a good balance between how good they look and how heavy the file is, for performance purpose.
- If possible, make complete sprite-sheets. Else just separate your assets with either clear naming or organised folders.
Hopefully it help. Take all of that with a grain of salt, It's just what I think about when I look for assets ʕ´°ᴥ °`ʔ
