Mate, you've made a name for yourself. Your characters and animations are top notch. You've hit the sweet spot. The style is clean and different than everything else available. You are massively under charging for your work. We all want you to make more, and the economy here will support it. Make this the starter pack. Start releasing supplemental packs. Charge 10x for them. Once you have a few, put them in a bundle. Etc. Take commissions. Make this more than a hobby. We want - and we will pay for - more!
