I tend to find graphic art where you have similar colors, for example your is blue and black background and the foreground is light blue, and the images are complex it makes it less appealing, go for a more simplistic approach, instead of blue cloud things and light blue stripes maybe add an inner shadow onto the text and drop the transparency on the layer to 0 if u use ps, makes it look neat, you can add different colors to the image text to get some neat effects
