I guess you can't make everyone happy and I agree, there's a lack of organic, goth and dark templates. However making a template takes 20 hours, at least! If you develop a free template you try to make it generic enough to appeal to a relatively wide audience.
Since you know what you want I think you should try making it yourself. It's not as hard as some people believe. You just need a pretty good idea of what you want, a good sense of color and shapes (which can be learnt ... you should see my first website!
) and start experimenting. I recommend using Fireworks for graphics. I guess Photoshop also works but I've always prefered FW.
