Thanks! And first - let me say they're adorable. Such great sprite work.
I totally understand trying to avoid stealing. Perhaps there's a way you could skew the art or use watermarks to prevent that, but still show off the designs? Personally, I'm much more likely to purchase something if I can see what the asset actually looks like - "Skate Animation" doesn't really tell me much about how it looks or how detailed it is. I also do mostly work with the GameBoy, so I like to gauge if the art can be 'downgraded' to fit with the color / size limitations of the gameboy tech.
I've made a few purchases on itch that I've regretted because the authors write up sounded like the work included more animations/details than what was actually in the pack. ABSOLUTELY not saying your stuff is guilty of that, you're good. Just thinking it'd be more likely to sell if we can see that.
I'm also noticing the skate stuff in the page background/preview image now too - it wasn't immediately obvious before (unless you changed things).
Anyway- love your stuff, will probably pick this pack up :)
