I don't think you're emphasizing what you think are your biggest advantages over others.

Your main screenshot is static, which means it looks as basic as any carbonmade/etc. portfolio site already out there: boxes on a screen. Since your page customization is fairly low compared to your competitors, you're all in with this sliding design, and you need to put it in front of everyone in a big way.

Does HTML5 mean anything to non-developer types? I'm not sure that everyone associates HTML5 with "works on all devices". Does your target market know multi-device display is a problem (and is it a problem with your competitors?) If not, you need to explain why you have something better to offer.

Also, personally, the Steve Jobs-esq language (i.e., "Show off your work in the most incredible way.") is a little off-putting, especially if all one can see up-front is static boxes on a screen.

Agreed with everything you mention. I'll update the front page of the website and duplicate the Sliding Boxes effects on the main screenshot.

I'll rewrite some of the language to target artists instead of developers. Thanks for this feedback, marketing is definitely not one of my strong suits.

Agree with you, sir. I'm not the target market, but I'm not entirely sure how this application differentiates itself against the bigger names in the space (namely Carbonmade). I'd be interested to hear what the OP says.

Carbonmade is plain and basic. And while I tend to believe that less is more, the only real customization they offer is allowing their artists to select between 2 different background colors.

With Sliding Boxes, my goal is to offer artists a more beautiful and customizable canvas for their work. Boxes on the portfolio's front page slide to reveal other artwork. And because it's built as a one page application, page transitions are sublime: http://lucalagreca.slidingboxes.com/
