Dizzi is right you are rushing your sigs.
Its better to have 2 good sigs then 5 alright sigs.
So take your time look at some tuts or download some .psd's to help you out.

Well the sig isnt too bad it has potential.
Dont put your c4ds in the back because it looks like you just slapped in a render on it, im not saying to not put them in the back but also add some on the render

Work on the text , text is very important too you may have a shmexy sig but crappy ass text and that ruins the whole sig.
And ALWAYS try to lut your text as close to your focal as possible
