These are intended as helpful, but with a mind that I do this sort of review often ...so, take it as you will:
1 Off-white website with a logo that's a different off-white draws the eye...either make the logo match the background color exactly or border the image so that it stands out
2 I'd recommend a landing page that's not just 'instant storefront'...either in the banner, or on the landing site that defines what your company does...then let folks click into your inventory. Until you're Amazon of rare woods, you probably want to let folks who come to your site know what you're about without click-throughs. Additionally, this will let your site be easier to search for if there are more keywords to parse in the initial page.
3 In the Shop All page, your filters are a little weird...you can't do sorted by price then adjust the price window on the left. I'd recommend perhaps another pane with filter options (aka: Amazon style) that eliminates off the primary pivot vectors you'd imagine folks would be interested in (price, customer reviews, in stock, featured, etc).
4 I know the 'Add to Cart' button is part of the template you're using, but as previously mentioned, it's hard to avoid...unless you put another button on the same pop-up that said "more info" or something that took you to the details page instead of just 'insta-carting' the item...that'd be better.
5 Wood details page, I'd give at least a Wikipedia listing of what the wood is, where it's from, it's properties, etc...fascinate your buyers with this rare Bloodwood block, from tropical South Africa, known for it's luxurious scarlet finish and can be hard to work.
6 Navigation pane, I'd consider reworking into either a collapsible tree or groupings...don't make folks scroll through a navigation pane if at all possible.
7 On the pages where you have share links (Facebook, Google, Print, etc), the print icon does nothing on Chrome.
8 On the newsletter adding success page, you misspell receive (

9 Your 'contact us' page is a little weak for a business. Recommend at least a P.O. box and phone number in addition to the default form contact.
10 Your Wood Identification page is extremely helpful...but you could really do to format it better so it's not a wall of text without distinction from one wood to another. Perhaps another tree with general, wood types, recommendations? Also, a weird item is that your *, **, *** system doesn't mention what it means when the wood doesn't have an * next to it.
Not sure if this is something you can adjust, but it feels weird to me that your left panel scrollbar covers just that panel, while the right panel scrollbar covers the panel AND the banner.
11 Stabilizing wood section either is cut off or you're missing a period at the end (hard to tell)
12 Most of your open text fields are formatted oddly with weird line breaks. Be consistent across the paragraphs/etc with either a double carriage return or a single
If this is your first website...kudos. It's not easy to make a commercial website with payment instruments.
Hope this feedback helps! Good luck!
