Also why is Raising on there? And where is Splinetic?

I'll comment on all of your sigs in one post here.

They all seem to be a bit bland, with not too much going on in the background. Also the renders you are using seem to all be badly cut out, which is leaving unmissable white areas that make the sig look a little sloppy. Perhaps if you added a background and were more careful with the renders chosen/are more careful when you cut out the renders you work will look better.
