Very nice

Well I do like the solar flare effect in the background as she emerges on the scene to fight evil people doing evil things that should never be done. Suddenly they quit and give up for no reason while she laughs at them.

The mask is cool. I also like the use of green here to give her more of a cool dual effect look to her effect. Similar to Sailor Moon except with a sexier outfit which is pretty cool anyways. She looks happy until you make her made probably.

Overall, Sailor Catastrophe is awesome.

Wouldn't she be better suited with "cat" ears then

the name "Cat"atrophe is in there.

Oddly proportioned in anatomy but you are great with coloring and lighting.

I especially love the hair and shines off the black. I myself have trouble with that.

It's good, just needs a bit of practice in anime anatomy.
