Changing layout shopping cart

Below is the layout of my shopping cart, produced by the shortcode [woocommerce_cart]. I have two questions:

1. The blue circle on the left marks some very small x’s that can be used to remove a product from the cart. Is there any way to change these x’s? Preferably into a bin icon or otherwise something bigger?
2. The red circle marks the fields with the quantity. The quantity is not clearly shown. Is there any way to make the field larger so that someone can see/change the number of items?
