Poor image fro a good prompt

Not sure this is really a bug but I am always experiencing difficuly with the image output from Firefly. I ask AI to create my prompts, which I validate but I always get really poor images? I have emphasised the parts of the prompt that are important but I end up with some mutant form of what I'm specifically asking for?

Getting a bit tired of it now as I thought this was supposed to be intelligent? What am I doing wrong here?

Here's my prompt;

Portrait of a happy animated young woman in casual streetwear (hoodie and jeans/shorts) in a dynamic crouched pose, reaching one hand forward toward the camera in sharp focus, shallow depth of field with blurred background. One hand extended with fingers gripping a mobile phone in a landscape orientation. Professional studio lighting on white background, commercial photography style, bokeh effect, hand in foreground crisp and detailed while model's body softly blurred in background on a white background.

Here's my results;
