Hold on to your trousers No bumping untill 24 hours after you made a post ^^ As for the sig: seems stretched to me because the lenght of it is far more than it should be actually. Reduce it by about 1/3 and will look more in proportion. Apart fro that, either work the render to fit the bg or work the bg to fit the render. The colours of both are not really matching
Meh, there are always certain trends in sig making. The one you made there closely resembles grunge, which is for most people seen as a thing of the past. These days they tend to work with C4ds, smudging, stuff like that. But for me personally, I like a bit of old school every now and then
And a crap load of splatter brushes. To the sig: Try to get the colours to fit more, and the chainsaw kind of.. blends out weirdly. Try to change the background maybe to the green on the render. You should try going through the tutorials section, even if you don't follow them exactly you can learn some new tricks and techniques that'll help you make better tags.
Yeah i notice there is alot of smudging in my opinion i dont think it looks all to good but meh i like the old type of grunge style
