C4D usage or what mate!
It would be a really nice sig, if you had some brushes that matched the flow of the signature. Brushes behind the C4D, then set the C4D to either Overlay, or make it a clipping mask. Right now just looks like you've used a render, and 1, possibly two C4D's behind. Imo, the renders mask should be kept the original colour. Text needs working on. It doesn't blend, use the eyedrop tool to get the colour from your piece, and make the text that colour.
