This signature has a lot of potential to be a lot better. Effects decent but can be better. The long vertical rectangle on the right ruins a lot of flow of the signature, it also don't look good with the dotted border over it. Either change the border or the rectangle on the right cause they are clashing. Text is cool but can be better as well I believe. Maybe also sharpening the render some just so Ken can stand out more and grab my attention more. But overall it's nice, I hope you make a V2
