your best is Nr.3
best blending and atmo.
-is your text supposed to be readable ?
if....
-yes ,then use a other font ,placec it near to the focal.
-no ,then use a smaller font ,much smaller, again play with the focal.
if you place the text far away of your focal you create an eyeflipping-syndrom^^
add some effects to give it more epicness
create more depth by using the dodge&burn tool and the blur tool (sharpen the focal, blur the edges
,but not too much blur^^)
your lighning needs work.
-take a look at the render, it's not coming from the right.
add some flow to your sig, movement, something magic......give this dude a pop-out effect....
like this
the text in this one added the final touch to the sig. not supposed to be readable but you definitely
take a look at it .
it's looking like he's falling/leaning back into the stars/ bubbles , everything goes with the flow(movement is to the top right)....
here i added the dragon to this nice girls back to create some sick art.
and the text here is placed near the focal, otherwise it would destroy the sig.
