Hi @eva_greene,
For a more professional Shopify layout, I would review the store in three layers:
1. First impression
Is the homepage clear within the first few seconds? Visitors should quickly understand what you sell and why they should trust the store.
2. Product page quality
Check product titles, descriptions, images, variants, size details, shipping/returns information, and trust elements.
3. Technical/store health
Make sure the store is not carrying slow scripts, oversized images, old app code, or missing product content.
Design matters, but a professional-looking store also needs clean product content, mobile usability, and a simple buying flow.
Once you are close to launch, I would recommend doing a basic QA pass on mobile, product pages, cart, checkout, discounts, and page speed.
If you share the store URL and what kind of feedback you want most, people here can give more specific suggestions.
As a final cleanup step before you start sending traffic, Checkpoint: Store Scanner can help check for leftover app code, slow scripts, unused metafields, large files, product content gaps, and discount issues.
