Ronald Sprite for Visual Novel called Trapped

Do you flip your drawing while you do it? If you give this a careful second look, you'll notice that the sprite is squished to the right, particularly from the shoulders upwards. It's something that you can mostly fix with grid distortions in Krita/Photoshop/Mangastudio 5. Additionally, I'd suggest playing with line weight to give it more character and: if you draw on paper and then scan the drawing in, consider drawing on a bigger piece of paper to have more control over the lines and avoid trembling; if you draw on a tablet, you can use various lines tools or draw over a blue sketch on a different layer so that you can make cleaner lines (these are particularly noticeably not clean if compared to the buttons on the lab coat, which look like they're drawn with the circle tool and clash because they're so perfect). Finally, it's a good idea to check your values, when drawing sprites. The skin here is really, really dark, so much so that there's almost no difference with the eyes, maybe making it a warmer and lighter brown and shading that brown with a bluish purple on a multiply layer would make the whole thing pop a bit more.
