As motsa says, it's not that dmoz hates you, but rather that your site doesn't give the impression of having much content.
The first thing I see is a "Buy Things" link, and I immediately think 'oh no, another poor quality site cobbled togther to get people to buy things'.
Next there's a "Wall Paper" link which contains four images. OK, so that's content, but not very much. Under that is a link to "galleries" which appears to go back to the front page. I realise now that it doesn't actually do that, but I thought it did the first time I went through, making it looking like a broken/misleading link.
Then there's "Games" which pops up a small window with a black screen saying "loading". There are no flashing progress dots and, since it opened a new window with no nav bar, no throbber to tell me if it's doing anything. I got bored after 30 seconds and closed it.
All that's left now is "Links", which I would assume leads offsite, and a "Mail Me" link.
From a reviewer's point of view that gives me 4 images in return for you trying to sell me things, a broken link, a 'game' which doesn't do anything, and nothing else.
I realise that your site isn't really like that, but that's what's found from a quick glance. All the other images on your site fail to show up as links to me because your mouseover code doesn't work in my browser (Mozilla 1.1) so I wouldn't have clicked on them if I hadn't read motsa's post above.
I think if you want to get your site accepted in the category you chose, you'll need to make the content more obvious. I'd put all your work onto a page clearly labeled "image gallery". Even adding the text "click on the pictures for samples of my work" would help. I'd also move the "Buy Things" link to somewhere less prominent. Seeing that as the first item on any site leads editors to think that the purpose of the site is to sell things, and I dare say that ordinary surfers might feel the same way too.
To sum up, dmoz doesn't hate you, but if its editors can't easily find good content, they soon give up and move on to a more promising site.
