It's definately an improvement! Text is better, c4d is placed properly. Obviously you have a lot to learn so I suggest you just keep practicing and reading tutorials.

I think Draywin was referring to the brush tool, wich allows you to draw using a brush, if you go to the top left of your screen (I think lol) there will be a button where you can adjust the shape and size, if you take a large round soft brush (soft means the edges are....soft) and go around the outer edges of your signature, it will darken the edges, this is just one of many ways to bring out your focal tho.

To apply an image you make a new layer and go to "Image" at the top of your screen and select apply image. It will copy every visible bit of your signature onto one layer wich is usefull sometimes.
