Let's not even try to discuss whether this is a valid take on "perspective", and just deal with the image :-) It's an endearing shot on an emotional level. The way the "antlers" match the fur is quite amusing. I wish the santa hat were not hiding behind the antlers; I'd have tried to fix that. The BG furniture is very distracting, especially the wooden leg, so you might have tried to find a better place to set up the pose. On the other hand, maybe the dog's not cooperative? What do I know? Anyway, I got a chuckle from this one :-)
Nothing much in the way of a different perspective in this. You got down to his level but maybe a real closeup at the widest angle would have yielded better results. IMHO
Excellent focus. I think with the pillow and the rug's pattern, I might've done this in BW so that we focus less on the busy colors and more on that awesome face. Maybe crop it tighter?
