System 3 Acrylics

I've been using Daler Rowney's System 3 acrylics since I was first introduced to acrylics in school art classes when I was 14. I have a few tubes from W&N Galleria and a few other student grade types, nothing artist or professional grade just yet. I mentioned over on Pete's most recent video that the largest work I had done was a mural and that I'd post a few photos to show him, and that was painted entirely with System 3 acrylic paints.

For anyone that is familiar with the Mass Effect Trilogy of video games, this is what the space craft details are based on, whereas the body of the mural itself I used photos of space taken by NASA.

For folks that have used other brands, what would you recommend as the step up from System 3 and Galeria student grade paints?

The mural itself. It is 8ft from floor to ceiling and I can't remember how wide. There is a can of orange tango on the stack of boxes on the right if you want an idea of scale.
