Your flow goes something of the lines of this:
left top left vertical top right. These are your line directions. Compare these line directions to your render. Is it the same? Absolutely not. The render's flow is only vertical. Now, its not to say that you can't include alternate elements that go in opposite directions, but currently, there is too much devoted to flow lines that aren't the renders flow, which makes it look poor. Also, with regard to spam, so much is thrown on there, it detracts from your focal. It isn't discernible at this point. Also, the current spam detracts from what could have been decent depth. See that bulging layer to the left of the render? It takes up too much space (due to its spam) and kills your depth because of this.
