Excuse me for being a big ignorant, but exactly what is this spine art, that all of you keep talking about?, maybe a graphic example will help me to know about it.

thank you so much Pavolink!!!!!

 

Looking at my game's collection across all platforms, certainly it's not the best but not  the worst, it could be improved, because right now the spine art feels uninspired and blant.
