I liked it! Ria's sprite is so cute, I love her expressions and her outfit a lot, you put a lot of detail into it! Especially when it goes out my goodness lol. The special mix is crazy I think I tried it before but hadn't gone back and tried it! Great stuff. I love that you can just be like ok here's one, bye, very professional lol. And Marin's personality is fun! I love her unabashed nature. Honestly what a good character introduction!
I think the formal nature is really well done, it's quite well-fit to the size it's aiming for as a project and I appreciate that. Great job!
