Hello, I am a graphics programmer, and I have about a year of daily experience in post processing and creating volumetric shaders not counting all the research on different post processing and graphics effects that I have done outside of that. I can see from the trailer that you game already has some good post but if you want anything more complex or want to upgrade your graphics then hit me up at aduck1753 on discord.
(willing to work for experience but a little money would be appreciated)
