Shop Page Picture Size and Columns are Wrong

Please help. I have added a few products and the shop page looks totally wrong and nothing like the demo. I am using Rustik Theme with the Woo Commerce plugin.
Problems are with the shop page
http://aikanbijoux.com/shop/
and category page
http://aikanbijoux.com/product-category/indian-candy-collection/

Here is a link to the what the demo page looks like:
