Hi Meriç,
Well you just made a sale :)
Your shop is very diverse, and if you had more items, I might advise moving the cat toys and related items to a separate shop, and keeping the other one for the woodwork and more serious decor items. However, managing two shops is more work, so I don't think I'd worry about it until you have enough product to really fill up two shops.
Most of your photos are good - clear and bright and attractive. Some of the smaller items could probably use a close-up for the first image so it's easier to make out the details.
You could be doing a better job on your tags. They're not bad, but you have a bit of repetition, and I saw a few single-word tags. Remember that you get those category tags for free, so if you have something listed in the "cutting boards" category, adding "cutting board" as a tag is a waste. You'd be better off using "wood cutting board", because that's a specific phrase people search for commonly. Incidentally, I'd probably add "chopping block" for the thicker boards. Other than that, just go through, tidy up the tags, and make sure you're not using single word tags or phrases that are already contained within another tag (for instance, "live edge" as a tag is redundant when you already have "live edge board" as a tag.
I look forward to dining by the light of my new tea light holder :)
