Your composition leaves something to be desired. The stocks you pick as your base layer usually don't fit the image you're trying to make, and then the sharpness of them takes away from your depth. Your C4Ds I will admit create a decent flow, but it's not really appealing, nor does it blend too well. You should stop using the color orbs is such great amount, it's distracting. The Clipping Mask text is usually not appreciated on most of the Tags that I had seen.
You're pretty good technique wise, but you need to refine how you deploy and use those techniques. Keep it up man ^_^
