first of all...learn blending if udont already know what it is then let me explain

blending
n.

1. the prosess of making an object or person blend into the background of an image, this technique can be obtained by using the lasso tool or some other type of selection tool in photoshop. first set the feathering rate to some number between 10px and 35px more or less if effects need so, then place your render over the background of your sig or image and select the area u want to blend...

there are two methods to selecting this area...

1. trace a outline around your render...keep in mind it doesnt have to be perfect, when u have the area selected press ctrl>shift>i or go to select>inverse.

2. select specific areas u want blended example. the right side of the render...or the left side or specific parts altoghether..

in both of these methods you press delete after you have selected your render parts.

then if needed finish the sig off with some overlaying brush effects..

also the text needs work you also shouldnt use outer glows on these types of sigs...and the texture almost looked like u filter whored it...you might just try basic brushing that works just as well the render just needs to be blended more
