woocommerce single-product page design

To whom may received,

I am trying to setup store using woocommerce, while i setup product, the single-product page shows “product image” is just too big and it just not using 500px as per setup in woocommerce setting. sample page as is sample page . i hope to get the product image on the most left with 500px in the page; title, description, add cart, quantity, color on the right; and “shop sidebar” too. But it doesn’t show correctly. not too sure can you advise which part is went wrong on my page? Thanks.
