First thing I did was to clone out the sidewalk and the building behind the moose. Next I took a photo of a lion and ereased everything I didnt want to show and placed it over the mooses head. Desaturated the lion head. Used the warp tool to extend the snout so it would hopefully still somewhat resemble a mooses snout. Enlongated the fangs using the warp tool. Used the clone tool set on darken to fill in the edges of the lions head to blend in with the moose. On an adjustment layer I lowered the green saturation a bit. Done
