Well im not sure i am a huge fan of this as everyone else is. It could be the render giving this the cherry on top but the blue streak is very distracting. I say tone that down and sharpen the render. But also a texture over this to make it less bland. Some grundgy spots but not too much to take away the smooth feel to this.
That being said i don't hate this sig. it is actually executed really well but could be inproved upon. Good job bud!
