Yes there's no magic formula other than constant attention to every avenue of promotion. Every Free site, Blog, and Gallery you make should have your LL link, as well as your Sig on Discussion Boards. Make your own banners. Don't miss any opportunity to push your site.
The design of your site looks real good and its got lots of 'Sticky' material for Bookmarkers but I don't see any Link Trades. Start building these up - its a source of traffic and helps your SEO.
Apart from that, as Lowry says, your site is still young. Keep persevering and I'm quite sure your traffic will build and build.
