Such bright cheerful images. Two thoughts:
-the font at the top with the navigation (Home, watercolors, about me, etc) is a bit small and scratchy, hard to read.
-on the about me page, the stark white font on the stark black background was hard on my eyes. Made me want to skim it fast and get out of there. If you just barely soften the black background, and then make the white font a softer extremely light gray, it will LOOK like white on black, but not irritate eyeballs.
Best of luck on your website!
