Ahm... what do you expect it would become exactly? Because there is a lot work to do here IMO and you did something you shouldnt do.
The bricks effect shoudl be removed. The blur isnt well done. The plaster effect isnt really well there imo.
For this to be actually good IMO, there should be 1C4D around the render, and one fractal, on one of the corners (depending on fractal applied)
Also, you should work lighting, like creating a vibrance/contrast layer and try to ajust settings. Use your selection tool and cut unneceessary parts before doing this. If done properly, then id should improve. I hope.
