The coloring is ok but those proportions are all wrong. No breasts are that round, even with silicone. They have to be as hard as rocks as well to maintain that shape. Her waist is so crushed in several internal organs have either ruptured or been shifted to places they shouldn't. She probably gets constipated a lot. Her shoulder is scrunched up way high and, realistically, she should be falling over. Her face and pose is also slightly vacant, the angle she's drawn at is a passive, generic, tamer boobs & butt pose.
Overall it's a generic wank pic from someone who bases anatomy of hypersexualized drawings or photoshopped porn actresses. I think the artist was going for a playful, sexy shot but the subject raises too many questions for me to appreciate the eroticism.
Like, did her dress pop off magically? If so, is it because it's after midnight and the spell expired? If that's so, why didn't her underwear also disappear? That corset and panties look to be a matching set with the dress, unless Cindy owns that lingerie herself and put it on before her godmother changed her dress? Plausible.
Then the slipper. According to the story she lost her slipper AFTER the ball, but here she obviously still retains both of them. So that must mean she is GOING to the ball, which then indicates that either her dress has just been summoned or this is a magical hiccup. (Her godmother isn't shown to confirm when exactly this takes place.)
All in all, it's not bad, per say. I feel it's generic though. Nothing too different from a Liefield pin-up right down to the hiding of feet. It'll get you started but you can probably use your sister's barbie doll to get off instead if this is what you're into.
