I think in part you may be having issues getting sites to link to you because there isn't much of a "story" with just selling layers.
You might want to try posting "How To" articles to your blog, even for things that you think are really simple to do with Photoshop. Maybe even a link on the front page of your site that just says flat out: "Here is how you would use these layer styles" (with lots of screenshots).
Also, you seem to have done a large amount of work to generate the actual texture files, are you selling them directly? I would guess that the market for texture files for 3D work or whatever is larger than the photoshop layer styles market.
Thanks for posting such an inspiring and detailed analysis of your launch and first sales.
This might also impact sales to more novice Photoshop users; being able to see how to get great results from the product you're selling could be a big draw.
