I get the idea of the photo but the shutter speed at 1/100th.sec is way too slow for this type of shot because it blurs the action. At least 1/500th would garner greater results and about f:11 / auto ISO. I have the same lens (TAMRON 18-400mm) and it's brilliant.
This happened so fast one minute it was lying down it just took off no time to mess with settings get your point though
