yes, yes it could. You went into no detail at all, so it’s literally up to the reader’s imagination. photo touch up could mean literally filling in freckles, well use the eyedropper tool and draw over them. Color science could mean checking the color profile of your monitor, the colors in paint are HSL. Retro pixel art is literally just drawing, you just don’t get the help of pixel by pixel drawing, you’ll have to manage that yourself. Your response indicated nothing about how you use GIMP, and honestly, I doubt you have used any really in depth features that Photoshop provides.
then why is every linux advocate stating that all that matters is picking your distro? If the system needs to have the OS preinstalled then the distro doesn’t matter at all. Yet that still really isn’t the problem. Installing an OS from a flash drive (distros are just as easy to install as windows is and people have been installing windows fine from hard media for decades) is a different realm of troubleshooting than driver issues. Either linux is ready for people to start installing any distro on their gaming rig to migrate off of Windows or it’s not. And it clearly isn’t.
