I created my portfolio through art station and added what I thought are my best pieces of work. I didn’t want to add random pieces as I don’t my portfolio to look messy, I based this again of the job I applied for for my mock interview which are well know for their grungy themes games. I added some 3D models that I completed on Maya and substance painter that I had used for Dining room.

Here is a screenshot of the home page of my portfolio, I wanted to put the biggest model at the front as its definitely my better work.
