I said before and I will repeat; body modifications are a different thing to creation. They are two different semblances, and you should pick whether you are going to be modifying someones internal physiology or creating external physical structures out of aura.

Adding a pair of wings to someone's back is okay, as it'd be like wearing an awkward jetpack. Adding Gills which allow them to breath to their neck is not, as you have to magically bypass their skin and a bunch of muscle and veins to filter the water into oxygen which is directed to their lungs. One or the other, not both.

I wouldn't go so far as to literally create things such as food, as you're basically just shaping aura into the shape you want it. While semblances appear to be magic, one of the few rules that magic has across the board is no creation of food from nothing.

Basically, if your OC ate the food that they drew, they'd feel full but it would be worthless nutrient-wise. They'd still die of mineral deficiencies, even if they didn't die of starvation itself.

And I'd make the elemental aspect such as fire/water creation a dust only interaction, not a base ability that then gets enhanced with Dust. Basically the semblance allows the user to have a much finer control of how the Fire Dust manifests, like how Weiss uses her Glyphs for finer control in Breach to do things like make Ice Swords instead of only throwing ice shards at everything.

Also creating Dust from the drawing? Big No. They'd basically just be drawing a pretty crystal that wouldn't have any mystical properties.

Plus, please remember that semblances require the OC has aura available to them, and should not be permanent effects. Even Ruby's petals fade after a few moments.
