I've used genetica extensively. It is a versitile and usefull tool that can prototype ideas and export them with normal maps, but it is not a tool that creates finished products.
My suggestion is to take thoes textures and put them into photoshop and add the details that would make them feel more real. Use thoes to make Specular maps for the engine. Adding some dirt would help kill the overly shinyness.
You might also want to take a look at the depth setting on your Normal Maps. They look a little strange in some places.
Other than that, Welcome to Mapcore.
