The text is horrible. There should be more of a lightsource in it like your previous one, and you put the C4d/Brush lines over the render. Your render is usually supposed to be on top. Also it is too big. Next time lower the height. 150 is usually a good size, but sometimes considered too big as well. Work on adding some flow and depth to the signature. Try out some tutorials and you will learn some more techniques. Also practice using the sharpen and blending tool.
