First rule of photography is: NEEDS MOAR LIGHT. After all photography is literally light painting.
First question: what do you have now in terms of taking photos? Pretty much anything made in last ~10 years can create decent photos, but advice may differ.
//EDIT:
I took a look at your uploads. Good stuff. Take a look at another thread: How to get more publicity? - loads of good info there posted by long-time creators!
As for photos: anything “product photography” you’ll find will be good, just make sure it’s not one of those “you have to have $5000 worth of gear” type of vids.
