Make my shopify store look nice

I have graphics and a logo but I need someone to organize the store into a nice more professional looking format. Mostly experience organizing the shop and using pre-existing graphics to make the page look nice. But not opposed to graphics being made if it comes to that. The shopify store is cameoanderson.com and will feature items with my art on them exclusively. I want the focus to be on fun but still trustworthy. Right now it looks very home-spun. I do have a logo and wordmark to work with.
