Thanks for all the crits, much appreciated. Thanks Rescale for the useful overpaint, I followed your advices. To Shepeiro : could you show me a little example of your sopecular map workflow as described, I can provide psd if needed.
This is a fast rework, just a maya screengrab with IcUberShader default settings. Light setting's not so useful to show up the specular details, anyway I think it's better than before.
