Hmmm... Sorry dude, not feeling this one at all. The bg is not appealing. And there's not very many cool looking effects. Sorry, Nice try
Text, colours, focal and depth are off... First, try and get a flow for the sig from the render which u choose which choosing the flow insert colours that can work not comprising either Background or Render (s). Make sure u keep your focal flowing and then add your text if wanted / needed. Continue trying you will get the hang of it
