I like the general look of the site, but it comes off as a bit sparse in places.
There's a bit of cognitive dissonance between Sam and Samantha. And who is Theodore Taylor?
The portfolio is clean, but the whitespace under the item header makes the page feel unbalanced. The ratio between the main area, the site header, and the portfolio selection bar makes the selection bar feel small.
On the blog, the cutoff for the preview text should be longer. The font use in the post title also hampers readability. I also would reduce the relative width of the navigation column and make the "Read More" target larger by using a button - which would be a good place to use the arrow font.
The suggestions about giving people (which people?) a reason to visit the site repeatedly are right on target. Without that, it's just an online portfolio and not wildly useful.
