Feed back on simplicity and Intuitive design Web App (mobile res)

[keen zephyr]

So I just started out design my own web app and I think Im pretty content with the what I have rn but I would like some feedback and I wanted how I would add filters option to the design so that it's not cluttery and is simple. It's my first ever wireframe design. Im gonna take the approach of learning while making something of my own and learning about solutions to problems I end up facing.
I want to make the as simple and intuitive as possible

The target userbase would be between 16-24 or something like that and mostly students

Depends how you want to filter. You could do drop downs with “recommended, price-low to high, price-high to low, newly added, etc” which would probably be more conducive for smaller screens than something like different checkboxes for “color, category, price, etc”. What kind of products will your web app be featuring ?
