Free lineart to color

So I made this little drawing some time ago and decided it would be fun to give it for people to color. You can download the PNG with the lineart and blank background here:

Either open it in your usual art software to color it or get it printed! Choose whatever colors you think fit I'd love to see and fav what you make, so I'll be super grateful if you show me the link in the comments (^v^)

This is for fun, so no commercial use of my lineart is allowed (therefore, no commercial use of your finished pic either, because it uses my lineart). When you post it to your social media, please, credit me for the lineart! A link to this deviation would be super cool, but not mandatory.

Someday I'd like to release a coloring book, it would be fun.

*When you download the file, it might look completely black on some viewers except for the heart. It's because the lineart is black and the background is blank.
