I find this drawing rather impressive for a 30 min drawing. He put a great background to match the drawing, it's very smooth and well assembled, and the character derpy hooves looks great, but doesn't seem all that creative, but i'm just nitpicking. I really like the color it's very bright and pops out, I specially like the detail on her main, it's fantastic. The muffin on the top left is a nice little detail, and i also like the look of on derpy's face it makes her looks ridiculous but i can still take her serriously. So i think my overall rating is 9/10.
Behold, the true ruler of Equestria, in all her Glory! Observe her adornments gilded in gold(en brown baked goods)! Worship her, for she is your new goddess and sovereign! Also because if you don't she'll steal your muffins.
