Let me help you with your sprites (desc)

Description: 1- The weird tilt to the side. Idk what that is or if you meant to do it, but it looks really unnatural. 2- The way the outline/border pixels look. They look like you took a mouse and just drew, and didn't really put effort into clicking and putting the pixels in the right place and making them look good. 3- Shading. I know you take pride in the shading, but it's really not too good. Look at someone else's art for shading tips and stuff. 4- The colors. I get that this is your OC(s) and you can do what you like, but I personally think there are too many colors, and they clash badly. Stick with a couple base colors, and make them work. 5- No Black and White! I assume these are meant to be Undertale style-ish sprites, but for being battle sprites, there's only colored versions! Try making a black and white version. My best advice is to start from scratch with a new sprite and actually follow some of these tips. G'day
