Practising Ideas on Photoshop

I had the idea to have a close up portrait of me taken that I could then take into Photoshop and edit it. The concept was "What's inside my head" so I wanted my head open and to have my interests and personality coming out of it as a thought bubble or something similar.
I wanted to practise editing a photo in that style and hadn't had any portraits taken yet so I used a portrait of a model to do this.

This is the image I chose to experiment with

This is was my initial idea for the edit

Then I kept experimenting and playing around with different tools and having fun with it.
