well here's my criticism.
The C4D was badly placed (No offence ), and it doesn't flow with the horse or the movement of the sig.
And it looks like you've changed the background colour a bit, maybe an overlayed gradient? But it seems too much, maybe flip down the opacity to 50%.
The font kinda looks Assassin Creedyish, but it doesn't fit properly.
Maybe go to dafont.com and search assassins creed and find their text and use it?
