Dawn Theme - Changing Product Image Size (Mobile) in Collection on Main Page - HELP

[YMTE]

Hi there,

I've searched extensively and can't quite find what I'm looking for + the 800 solutions aren't working for me for some odd reason. I'm trying to increase the product size on MOBILE for a featured collection on the main page of the Dawn theme. I've tried to change things in the Base.CSS, Component-Card - everything. Still not finding the right solution. On the mobile, the t-shirts are far too small for my liking.

Any help you can provide will be very helpful
