awesome.
but dont know about the small sig, and the text.

the sig without everything else looks cool.
the text could use a bit of work tho.

The text.. It needs a lot of work. RIght now it doesn't work with the sig at all. The sig would be better without those side things. TBH those 3 side things make me think your trying to cover up the parts of the BG that are empty and make it feel more full.
EIther way it's not working it alone would be much better.

The effectsa re nice and lighting is okay. I would have prefered for the renders head to be a bit smaller. But it's not bad. You just really reall need to work on the text and side parts.
