The design is quite nice. There are a few things I might point out tho.
First of all, text that goes on sliders shouldn't be done in photoshop. They should be done in the html. Not only is this good for SEO but your text is really low quality on the image (blury / pixelated)
You're also missing a favicon!
The three large hoodies at the bottom, shouldn't have text going over them, its hard to read. You should make it black and put it on top or at the bottom of them.
Also not sure if you noticed but these elements don't line up. Not really a big deal tho
If this is a serious business, I would just remove the memes sections. It's not professional at all. Save that stuff for your social media pages.
I know you want critique on the website, but did you use mockups for the clothes? It looks like you just downloaded a hoodie image and placed text over it. Using mockups makes it look a lot more realistic
