I just thought I'd post this up. I got the render from a render pack, and it was rendered by a "JJ Ramone". Thoughts, questions, critism, and advice is welcome. Thanks, Darasuum.
The render needs to be blended into the background. Take the text off it kills and the light source is off from render to background. Try to make non vector effects when using a render like that one. I would read up on some tutorials they will make you better fastest way.
IMO, it does not look real enough, i suggest looking at some stocks (perhaps some free ones) to use as part of the background. Again, as I suggest to many new "Image Editors" that I see: Experiment with the program that you use, whether it be Photoshop, GIMP, or any other program you see fit.
