The first 1, the second ones text doesn't really fit with the focal point and the background. Also, If you make the text greyish it would look better, get a soft brush about 10-15% and zoom in to about 500% and move to brush along the sides it would blend in better with the focal and background. also the white brush u used around the text looks retarded, but that is my opinion. On the left side upper and lower part of the render i see there is a low opacity thing erase that if you can, unless it is apart of the background you chose
And on the left side of the render is looks like there was a hard small brush used around it. Remove with a low opacity eraser
