Woocommerce Featured Products… images wrong?

Hi all.

I have added a featured product widget to an ultimatum theme that can be seen here: https://southporthosting.co.uk/aquastore/

As you can see – the images are tiny and are to the right, and the text to the left. Can anyone advise how to get the images ABOVE the text (ratehr than side by side) and make the images larger?

Alternatively, can anyone advise how we can set up a slider which includes all featured items (if this is possible)?
