This is a new sig that I recently finished work on. Featuring Rios from Army of Two Edit: Alternate version below. Darkened up some spots and also sharpened up some of the areas that I thought could use some focus.
Not bad, but you could use some pointers. 1st - It is lacking in a good focul point (somewhere for your eyes to be drawn to when first looking at the tag). This is due to the fact that the signature seems to be sharpened/blurred in random areas. 2nd - The actual render is kind of blended a little too much. He doesn't really stand out ,ya know? Good flow. Don't like the text. Keep it up mate.
I'd agree with HopLite, it does seem a little too blurred.And your focal point seems a little confusing. Maybe instead of making the Width of the tag so long, try using 400x200 Pixels. It gives a great size to the tag. Hope that helps . KIU.
I would make the render bit bigger and reposition it, just to make it stick out a bit that in away will create a nice focus point.
