Morning,
I have seen your project RayTracing - Phong Shading and have seen your description that "Need help to implement phong shading in a existing project in C++......" so on
I am pro Swift illustrator with skills including Graphic Design, C++ Programming and Ray-tracing.
I specialize in all kind of graphic design such as branding, graphic design, illustrations, cartoon and caricatures etc
Here is the link to my portfolio and profile

Do you have any example design to share ?
You can send me a message so that we may discuss more.
Yours truly
