Why am I not getting many likes?!?!

Luck mostly. New users need to create something pretty striking to stand out. Then a lot of practice, learning how to use stable-diffusion prompting styles etc. If you're lucky and score highly in a daily challenge you may get more likes if people see those creations. It takes time, practice and patience. Also networking helps some users. "Road to Mastery" has more info on how to accumulate credits for creating/following/commenting etc and there's a few chatrooms with info to help new creators on here! Good luck!
