Okay, so first impressions - it's got a very minimalist design, which makes it satisfying to scroll through. However, the blue background is a bit off-putting, along with the very large articles. I think, formatting wise, you should choose a warmer, more neutral color to go for your background. Also, keep the articles smaller, so that you can list more. Try and make it satisfying for the viewer to look through your posts.
When I clicked on your articles, they seemed very professional and cold-ish. Basically, we don't see any of your personality coming through your writing. This would be great for a journal, but not for a blog. It's okay to use first person to talk about your research. Make sure you also have an introduction and conclusion to your posts. Your audience should feel included, not disconnected.
Lastly, I noticed that you really like writing your articles in list format. This is good for posts like your Essential Oils for Skin Tightening post - I like how you elaborated under each bullet point. However, posts like your Health Benefits of Grapes article could use a little more description. It seems a bit bland and abrupt to throw a bullet list at your audience without another word.
All in all, a great blog! Very informational and well written. Just fix some things, and you're golden!
