I really like it! The first thing that stood out to me was the consistent style which looks so good. Some images are a bit darker than others but if you compose them a certain way, maybe the contrast will be more pleasing upon first entering the site but don't forget also, that as you create more art you'll start to look at the pieces you have on display on the website and determine which piece is the best representation of your art and style and you'll do some swapping as you grow professionally and artistically.
The only opportunities I see are:
-Are you able to name the images? When I click on them I noticed it says "title.jpg" to the right of the image. Im not familiar with wix but Im wondering if you can change that text to just show the title.
-Perhaps a quick revision to the artist's bio under the "about" page. I noticed only one misspelled word but maybe a few word changes could be helpful but this is purely suggestion. This could just be the english student in me coming out lol.
-This is also purely suggestion but I wonder how it might look if you changed "Home" to "Portfolio" and then swapped it with "About" and changed "About" to "Home" or "Welcome" and put one photo of your art on that page and then had your bio and then under your bio you put your headshot. This way when you go to your site you're greeted with one photo of your artwork followed by your bio (statement, style, inspiration, medium, history, or anything. the possibilities are endless) and then followed by a small headshot. Then the second page is 'Portfolio" with all of your artwork and then finally "Contact". The one photo of your art will leave them wanting to see more!
The instagram link is awesome! I just followed. Hope this helps! Looking very good
