4 Color Pixel Art Small Tileset

i made it as a 16x16 px tileset.

is free to use but please credit if you use it.

a small 4-color pixel art tileset i made to practice a little bit. im going to work in a fullcolor bigger pack with different assets, but i made this one as a practice challenge limiting my palette to only 4 colors. i hope you enjoy it. 

if you have any recommendation or tips you would like to give me please leave it in the comments, i'm really thankful! 

ps: if there is any format/file mistake i made please leave it in the comments, im kinda new to asset making so i'm in a learning progress. thank you very much! :)
