First, thank you for taking time creating a new sneeze drawing. I am happy you did! I know it can take time and effort to create new things.
Second, the way you wrote this introduction was fun to read.
I like how you write. Solar flares themselves are cool to see in space videos. You had a smart idea with creating a space/dark background here for the preview image. It does remind me of a solar flare! A messy one XD
Mess is something I know some people really enjoy and I may not be one of them but I think you did a really good job with the detail of the messy flare erupting from the cavernous, irritated flaring nostrils. It is fitting for this character honestly XD Her sneeze reflects her name.
Drawing a newer character is tough but you did great with drawing her in your own way! The different colors for her hair/mane and the way you did her closed eyes and scrunched up muzzle are nice details I notice.
