Changing size of footer images on mobile + Textbox gap

Site URL: https://www.plantbasedpitstop.co.uk/

Site password is: pitstop

Im wondering if someone could help me out with, what I hope are, simple CSS amends.
First off im trying to reduce the size of an image ive got in my site footer on mobile - as you can see from the reference its coming up HUGE. Id like it to sit opposite my copywright copy - as per desktop view.

Secondly id like to reduce the gap between by text boxes (see reference attached).
Ive tried a number of ways but having no luck so far!

Hugely appreciate any feedback.

Thanks all!
