Lots of glass added to her gear and "costume". I figured I'd make her colors very pale, since her powers both look and behave in a similar way to ice. I'm going for a "ice-queen" kind of vibe in terms of looks. I was really happy with how the dress and umbrella turned out.
The dress has this thin net hanging over what's supposed to be frills. This net has smal drops of glass attached to it, something that was present in one of the outfit sketches. There are also some small glass ornaments added to the top part of the dress, since it felt a bit empty up there. I didn't really feel like she would wear gloves, as she won't be cutting herself on the glass she controls - Unless that is how she goes down in her universe. Maybe she's careless and dies from being hurt by her own glass...
The umbrella was an unexpected but welcome addition to her outfit. At first, I wasn't planning on doing anything special with it. When I tried to create some kind of fold-able glasspanel design, it kind of looked like a blunt weapon to me. This reminded me of the magical girl genre in anime and how the girls sometimes have very large weapons, so I was instantly hooked on giving her some of that.
I did mean for her to be taller, but this works just as well.
She'll still be fixated on preserving beauty in glass, her dress will create an hourglass waist and she has a neat combat style - mage when far away, brawler when close.
Next step is to thumbnail for a good composition. I'll be looking to find a good mix of showcasing her powers along with her motives.
