Hi Bekka :-) Welcome to the forums...
The two things I noticed initially, are mostly aesthetic. You could use
some left and right marginal whitespace in all your writing. It seems
cramped, pushing up against the borders of the content areas.
Additionally, you should get rid of the table borders around your
images. They end up making the pictures look ragged. With the images
themselves, try to size them all so they`re the same height and width.
Varying sizes for thumbnails doesn`t look all that great.
What I`d expected when I clicked on "Gallery" was a thumbnail gallery.
For what I think might be a nicer presentation, you could take an
"example" of each product line, then place the thumbnail image of that
example---one for each category, so six in all----in a vertical column.
Give a short description of the category, then make the images a link
to get you into that area.
It would replicate the same menu items along the left, but just make things more visually interactive.
Beyond that, I didn`t easily see any way to buy something from your
site. That`s kind of important, right? :-) You could have a tab for
"Purchase" or "Order" or however you do this. Somewhere in there, you
likely would want a "Contact Us" link of some sort too, I`d think.
