For the first GFX there's no BLENDING at all. The placement of the render is really bad. The font and the placement of the text is really bad. Here's some tips that can make your gfx way better. First, find better quality fonts and background. Maybe like planetrenders. Second, try to blend your render with the background. You can smuge it but find the background that fits the render. Third, Try not putting any text of any of your gfx before you master good placement with your rendering, blending, and much more. Finding the right font and the right placement of the text is pretty hard so don't do that for the time being. Read some tuts and watch some youtube video! You'll get better!
