Well, the texture of the costume looks too hard-plastic for me, as well as being very thin looking and form fitting, even for fabric, but I do like the level of realism and Photoshop talent you put into this pic. It's like a hybrid between a
/cartoon hybrid and a retouched photo. It looks really cool to me.
Good work!
And I agree, you did well on the curtains. I think a circus tent wouldn't set her off well, especially considering Selina's sophistication.
