Why is the website laid out by project instead of by type of work?

I've made many portfolio websites and have done a lot of research seeing how other artist and animation studios lay out their website. I have found this style of display to be what works best for me so I feel motivated to keep adding to it. 

​

Will you ever change it to be portfolio based instead of project based?

Maybe one day, but when I started this website I didn't have much professional work to display and a lot of it was/ continues to be locked content for large periods of time before the final product can be aired. Because of these hurtles, I decided to start off with having the website be broken up by project so I could simply private the whole page instead of having large portions of various pages that were blank. It also gives me time to edit the pages before I share them so each piece can be displayed in the best way I can make.
