This is a very good photo but does not hit me as an motivational poster, shake it off? It might be because i do not understand what message you are trying to get across. 6
Hard to tell what this is; I know it's a dog! Right!? Well, those that aren't familiar with animals will be less likely to identify and therefore visualize.
This is one unique motivational poster. The photo itself is absolutely excellent. Focus, DOF, and the shutter speed you choose... all A++. The framing is also excellent, and I think your choice in colors was definatley a good one. As for your title... it fits well and made me chuckle before I saw the picture. :) nice work.
I taking it your camera survived the spray? I think I'd also try a little lighter color for the large intermediate matte since the dog is kind of low contrast..
