You're right, that does look less jaggedy. Thank you.
Everyone seems very helpful here :)

nice work

but I think her face is a little jaggy at some places and I would make the lightest black color even lighter here is a very small edit:

Gosh, you have such a good eye. Thanks for the heads up again :)

The whole impression of the picture is that it is cool. But cropping is strange and her figure is very assymetrical (on the left the outline of shirt is touching the breast as it should, but on the right there are additional 10 centimetres).
