Animal Portrait is a preset that you can use in Silver Efex that gives the photo an old look, I think it is particularly suitable for animal portraits. I made the preset for use in animals where the fine structure keeps the hair sharp with a soft grain, but of course it can also be used for other purposes, you can try that nicely yourself (I haven't done that yet). You can download the three presets below. Install them in Silver Efex. At the bottom of this article is a link to a brief instruction how to install presets.

Another example, the album with photos on Flickr:
All my work can be found in the photo portfolio. You can see the photos on Flickr. Here you can see the newest photo, if you click on it you can view the photos in bulk. You can switch back and forth between the photos with the arrows at the bottom on the side. You can also navigate with the arrow keys or swipe. You will see 20 photos per set, the photos are sorted from new to old.
