You asked for my opinion, so I will give it. First off though, What program do you use? And have you taken any Tutorials for sig/graphic making? If not, then try it. Im not keen on the sigs, though for what your doing, your good at it. I cant really give you a full on opinion as I do not know if you are using Adobe PS, which Is what I use, along with Cinema 4d and Bryce 5.
