I recommend you try a different program. If you draw hair like that, it looks like Rosy's hair is very messy. Try drawing on paper, maybe. I like the eyes with that little sparkle looks pretty cool, but the eye brows look like check marks. I don't really know what expression she's making when the mouth sort of looks like a triangle. Try making it more round. Try adding details to the nose, and don't make it just a line. The eyes look sort of creepy when they're all blue, try making the eyes white, and the pupils blue. Try not to make Rosy fit into these categories:



-Mary Sue (An OC with no personality, an OC with unlimited powers)



-Sans Fangirl (A girl who thinks they are in love with Sans)



-Yandere (A girl who will kill anyone who touches her crush)



I'll try to draw Rosy and I'll give her a personality here:



Rosy has a crush on Sans, and she's very short-tempered. She get's pretty angry when Sans is with another girl. She fell into the underground when she was around ten-years-old, and liked it there. She decided to stay. Sans is still unaware Rosy has a crush on him. Rosy is really shy when she's around Sans. Her soul is blue, integrity.



I know, it's still bad. I tried.:/
