It's the halo-ing around the edges to watch out for. (there's still quite a lot of that) When the borders start to become very thick and strong is when it's too sharp. A super secret (ssh!) trick I use when I want total sharpness and loads of detail is this: www.mehdiplugins.com/english/l… Download the plugin, apply it to a copy of your image with the original on a layer underneath, and reduce the opacity right down until you get all the detail without the effect being overbearing, then create a flattened top layer and sharpen on top of that. If done correctly, you'll get sick sharpness and detail like you've never seen, with no haloing at all. Avoid using on noisy, grainy images or images with compression artefacts, as it will make them sing out. If you get this though, you can always mask it out. Please ask if you need anything cleared up!
