its alot of sh1tty waffle in there so its up to u wether or not u wanna read, but im just trying to help u aswell as everyone else

aite
main thing is the border.....IMO, kills the tag somewhat

then, the area circled in red should be smudged or heavily blurred......then, following the direction of the arrow up his body, u need to blur it, but as u come further up the body, the level of blur should decrease.......
that SHOULD add SOME depth.....
the same goes for the arm, also in red.....
basically all areas that are further away from the foreground should gradually get blurry/less in focus......
this means that his face should be sharpened up a lil, but its already sharp enough IMO....

now think about the lighting......is the light source strong ewnough to be producing so much light on the shield (blue circle)......
of course not....
therefore, u either need to increase the strength of the lightsource, or somehow draken the shield.......i would personally go for darkening....
make a new layer and set it to either multiply or overlay......lower the opac. to sumthing like 50% (can be lowered or increased accordingly)......
thennnnnnn, grab a 0% (SOFT) black brush and start brushing in ALL of the highlighted area one the shield......once u done tha', grab a massive (say 400px) soft eraser and erase (quite far away from the shield it self, just so that the 'black' u brushed begins to fade - u should be erasing on the side of the arrowhead).....

then theres the text......
i have to say it does look dayum sweet.....but on this sig......uhm.....no.....lol
nah, it doesnt fit.....text should always be subtle and add to the sig, not take away from it (and thats wat its doing now - distracting the focal way too much and taking attention away from it)....


heres the circlified image:




yeah
loke i said before, dont take the essay thing badly.......only trying to make u get better
and i sure hope wat i wrote helps
