I totally agree with Vlad in this case, no real flow in the signature, and the attempt at blurring the background for better depth didn't work, it's over blurred, and hard to look at. Background blur needs re-doing, and leave around 5px around the render unblurred, just for better depth. The render looks amazing but the lighting is a lazy job in my opinion. Light source needs to be slightly brighter. It's a nice sig, but it's got a few flaws, no real flow, perspective or depth at the moment.
