Hey Nabil, not sure if you wanted feedback, but range sliders are among the most impractical pieces of UI. I'd consider leaving the radio buttons, or adding text boxes to help the user. Keep it up!

Since we are dealing with very large numbers and want to leave it up to the user to select their ideal range, I chose to not go with radio or checkboxes because I would have to add a lot. Any tips on what I can do differently?

The changes seem to be subtle but really shows your growth as a designer.
