This clearly shows the issue with the spacing across multiple sections of the design. While minuscule in difference at some areas, any small deviance from each other will be noticeable by people. Most will view it as "something is off" while a trained eye will be able to tell exactly what is off, the weight balance. This occurs because of poor contrast as a result of different spacing all over the place. There are more "weight" on the right, then on the left, then on neither and then back to a random side. This results in the design seeming off and messy, it is in other words the standard results of bad contrasts.
Speaking of contrasts, the use of background with the font color and some of the overall colors used make it near impossible to read. Using black on dark shades is the second biggest sin you can commit in terms of color use. The biggest sin being putting yellow on white.
