Alright, this is one of those people that I believe is vastly under appreciated, who also happens to be an amazing wildlife photographer.
 robbo is offer reference/photo packs here: http://www.furaffinity.net/view/17059556/
I've gone ahead and purchased the "reference pack" but I plan on purchasing all of his excellent photo packs. Having a stock pile of really good photosgraphy is ESSENTIAL for me as an artist who likes to attempt realism. Robbo is an AMAZING photographer and works extremely hard to capture beautiful photos and it really shows. he's also an extremely pleasant and polite person from the few interactions I've had with him. Even if you arnt an artist who could use the photos, you should give him a watch just for the amazing photography he offers. This is my way of giving back for offering such amazing pieces of inspiration <3
