I have to say, that i put quite a liking to this picture.
You have a good sense of anatomy as far as i can see.
I also like her facial expression and the dynamic flow in her hair.
You made a good choice for the color of the outlines, as it makes the whole painting more natural and vibrant.
Overall a very dynamic composition with all that lightning flashing around.
What pulls it down is how extremely sloppy your lineart is!
This is most obvious on the wing... thingies?
Their shape is so unconsistent that it really don't harmonizes with the rest of the drawing.
I can see, that you put much less effort in them than in her actual body.
And when we speak about her body... is her right hand missing?
I could say the same for those rings? and the lightning.
Even though they are supposed to be rings out of light i guess?
You can still give them some kind of shape, make them look like they have actual dimensions because like that they look just like sloppy drawn white circles, because that is what they are.
A ring seen through different perspectives is not allways a perfectly round shape.
A little tilt would make them way more believeable.
You also would agree that this is not what lighning looks like.
First of, lightning is not yellow!
Thats simply stylized.
You can make it like that, but it is not the best way to show real lightning.
And also lightning has kind of a shape.
Look at photos of lightning to see how it behaves and what kind of shape it has.
But as i said before, i like it.
When i compare it to previous of your works its an obvious improvement and that is great!
I hope you will hone your skills further so we can see much more great art from you!
