WebGL and three.js website changes

I have a space environment on my website where i want to make some changes. My website is created in PHP.

The space environment has been built using three.js and WEBGL, you must be good in this before you decide to bid on this project please. I will send the screenshot with the changes i want and also the website link to you as well when we chat on freelancer. This work will be good for someone who has the skills in this.
