I think the realistic head looks pretty creepy it all. :c
Look at e.g. Disney's Robin Hood, and how the hero's face has pretty human features, such as his eyes and expressions, making him seem more friendly, lively, and somehow more natural and less creepy. In a cartoon/psuedo-realistic world, it looks relatively pleasant and happy.
However, this dogman looks way too animalistic and expressionless and it looks more like some horrible monster made in a lab. Furries and IRL don't mix. Even anime characters have the same problem.
