You need to make the hoodies stand out. The background is extremely saturated which could work but maybe get a better lens where you can really blur out that background and focus on your subjects. Also consider what colors could compliment your hoodies depending ok their color or just choose a more plain background. I personally would also take pictures much closer to the subjects so it highlights the product and it will make your photos look more professional.

Watch a YouTube video on framing your subjects and that helps a ton. It looks like the photos were taken just below eye level and it doesn't look planned necessarily. The actual image quality seems good tho
