That's pretty good! I'm surprised the colours are so vibrant, most of what I've seen of watercolours grant a low-saturation effect. If I may critique, I'll point out that the lower half has a bit of a masculine build. Feminine hips are wider, somewhere around the width of the shoulders, depending on the body type. But overall, I like this very much! Niky's character in particular is fun to see in any style.

Also the lady you drew is :3c

But I love it, Nikys design is always so RAD :D

Thanks to both of you! I appreciate the critiques, it's always good to see the areas I need improvement in.
