HO HO HOPE you become a Newgrounds Supporter this year!
We're working hard to give you the best site possible, but we have bills to pay and community support is vital to keep things going and growing. Thank you for considering!
I made a cave tileset for practice and put it up on the gamedev market: https://www.gamedevmarket.net/asset/caves-tileset-9503/
If there's any kind of asset you'd like to see from me(be it 2D or 3D) just leave a comment with the idea. I might not do it if it's too common or specific tho.

Nice work :)
Neat. I wonder if you can pull off making a forest tilesets?
