Yes it's the basic products display, everything in hikashop can be customized, each thing as a class or a unique id.
You can edit all the views as you want.
The price can be moved in an other position, you can edit everything in css, or by editing the views, to edit the views you need some knowledge in PHP.
To edit the product page, you can edit the file "product / show_tabular" in HikaShop > Display > Views.
In the configuration of your module (HikaShop > Display > Modules) you can set the option "Display custom item fields" to yes. By this way the product details will be displayed.
For the images, the thumbnails have the same width, the height is set depending on the original file size. It can be changed, but a good PHP level is required.
When you edit the view "product / show_tabular", you can change the code to display tabs and not only text links. You can see examples in some showcase posted on the forum.
