Hello,
1) Don’t have access to your screenshots. Could you, please, explain in more detail what exactly you want to control? In the Theme Options > WooCommerce > Product images (these settings are default WooCommerce settings by the way) you can set the catalog image width and crop image according to proportions or use uncropped images if you need. There are no any other settings for the product images. So, what exactly do you want to change?
2) You can change the size of the price using below code in Theme Options > Custom CSS
.template-container .content-product .price {
font-size: 20px;
}
3) Use the custom code to add more space between items
.content-product {
padding: 10px;
}
4) Use the below code
.fancy-select-results ul li:hover {
background: #00bf84;
color: #fff;
}
Regards
