This was cool

I love the color on this it's nice and has some good lines and some smooth shapes I'm not too fond of the background I think you could use a better background maybe some trees maybe a sunset but something more then just the black background I'm just throwing a few ideas so the can be an improved background but anyways nice work

nice

this is cool

Good show

Funny thing is I actually recently started to watch that show. Have no idea why but it is pretty good actually. Nice character artwork of Dia as well. She looks ready to put up a fight for her friends and what not as well.

Like how it looks real close to the show's version of it as well. All I can say is that I am impressed by this. Good luck on future art.
