TBH your signatures are the worst they have everything wrong with itfirst just work on the render and always have it above all the effects not appart of it..Make sure the text stands out and add a border use good effects on the renders by duplicating it 3 times
Bottom Render:guassion blur-4.0
Second Render:Normal 50%
First Render: Overlay 60%
and maybe add a stadium in the background and set it to overlay and lower the opacity...
