If its function there is no suggestions really (Mayby performance wise, writing wise, but I don't have any knowledge on that)
The only suggestions I can give are the visuals again lol.

LOL, I am not good at visuals, Maybe you could redesign it?

Na, that
Instead of me doing the work, I'll guide you through a proper UX.
So lets first re-think the steps in order to do the function.

1. You're starting of with a header, seems fine.
2. Then you have a CTA (Call to Action) button. If I were you I'd ask the user to checkmark the selected filesize.
3. Then I think having a input field with the desired amount would be good.
4. As last I would have the CTA buttons (PUMPER & BROWSE)


I've made a quick sketch in Photoshop.
I don't want to go into to much visual so I will leave you room to be creative.

na thats ugly as fak
