I think it has a lot of promise. More so I think you should make YouTube videos.
Because 'if you are for real', then your personality and message are bigger than HTML and static images, in my opinion.
If you are mostly about selling your physical creations, then of course the site is a good medium for that.
(I like the T-shirts.)
Just simple titles (tooltips) so that we know where we are going when we hover over stuff would help.
I realize that if people don't have the character to seek, they don't deserve to find, but this is the internet, and people enjoy being led and enticed and it serves as a way to help to educate, stimulate, entertain or close a sale (if that's one's aim).
The example of Hovering over 'A man can do all things if he will' doesn't tell us anything about why to click. I know we want humans to be adventurous, but if they don't expect a portfolio they may be disappointed (for their own reasons). If a simple tooltip tells them 'Portfolio' they will know what to expect and go with the flow. Make it easier and make them feel more intelligent (by feeding them hints).
Do you make YouTube videos? I think you should in my opinion.
Thinking outside the box works wonders on YouTube.
