Hi Lynn. Just found this thread, so late.
I like the broody, dark feel of your landing page. Some suggestions which may be helpful:
You seem to have 3 different images as background to the scroll - the single tree, then the canopy and then the trunks. Looks a little disjointed. Possibly find a single image for the background?
If the idea is to sell the books, I'd make the buttons brighter. Hard to see at present.
Marie's comment about navigation is good. The bio at the bottom of the first page feels unnecessary. Clicking on About, where I expected to find your story, took me to another page which was friendly and chatty and told me your story well.
The couple of titles at the end of the blurb seem unnecessary too. I actually tried clicking on them to see if they led me to another learn more section of the site. Possibly give them a heading if you feel they should remain?
The search box is confusing too. I typed in Author just to see if it took me back to the About (you) page, but instead it took me your blogs. Possibly rename as Search Blogs if that's what it is? Or rely on the main menu alone?
Hope this doesn't seem too negative. It is a beautiful looking site.
