Worked on my first project with no tutorials

Hi :) Made "the Sun" today; this is my 2nd day learning. I have zero experience, so this is very nooby, but I had fun doing it. I started feeling more comfortable with the program, but I really want to improve my skills. Any tips, advice, or criticism is welcome!!

Also any cool plugins to check out? At the moment I only have the Mister Horse starter pack
