My first reaction is "this is cute and fun!"; it's a nice simple design with colors that really pop against the white. For a first attempt at CSS I'm impressed. The journal text is bright color pulled from the header image (always good to use colors from pics used in design) but not in-your-face as some of bolder colors (which really worked for the border and moods). It has a nice balance of warm and cool colors that are never too hot or cold.

I would suggest adding some padding to the left side of the moods or centering them. The green in the bottom links is a bit bright; the sea-foam or grassy green would have been a better choices given the background color. Also the text links in the content are a bit light. You want some more contrast between backgrounds and text colors for readability. The title and subtitle colors either need to be changed or centered (that green against the red has a strange effect).

Again, this is good start overall. I'll have to check out your gallery and see what other gems are hiding.
