For starters, stop using that obnoxious watermark/stamp.
Snapshots with horrible composition:
That second one, the model is not only chopped off, she's totally out of focus.
Ambient light won't cut it in this setting. You need to light the model with a flash.
Most of the series with Aneta is an improvement over your other work, but the lighting is still flat. You're using an on-camera flash or on-camera speedlight in this and others?
She's terribly out of focus.
You need to work a lot on composition and lighting. Be judicious in your use of ambient light. And when you do use flash, avoid making it flat. And kill that big-ass watermark/stamp.
