Overall the look is ok ... I like the logo, it isn't cluttered, and your message is easy to understand. The dark blue text on the water could be changed for more contrast, though.
I think your cart system could be streamlined to be a bit more user friendly and intuitive. For example, I go to "Birthdays", then click "Message". There are 2 images with prices and radio buttons. It would be beneficial to add some type of text telling me how to proceed, something like...
"Please select the type of bottle you would like, then proceed to select your paper".
On the paper page, again let me know that I can then go to "Accessories" to add more options. Just the large buttons with "Paper", "Accessories", etc., isn't a very helpful guide on how to proceed.
If possible, you may want to have a list of the users current selections on each page as they go through the system and customize their order; this lets people remember what they've already selected, and might help them with color/theme selections as they continue.
When adding text, then clicking "Order Summary", I kept getting the same text entry page over and over, then realized I needed to select the font and font color. A short message at this point stating that these must be entered to be able to continue would be a big help; just saying "None" isn't helpful.
A real nice touch would be to show, if possible, some type of image with all of the options selected, however that might require some intricate programming.
So, my biggest suggestion would be to fine tune the cart system, but overall it looks good.
