I see you've been working away for quite some time with very little recognition. There are ways forward for you as long as you can produce quality content. I suggest you go to @littlescribe and take a look at some of her tutorials. And as far as dark matter: dead in the water. Astro physicists have determined the theory does not work. You might want to go to suspiciousobservers on YouTube, there are some excellent vids on the subject. Blessings and good luck.
