Looks like there is lots of switching action going on--is it your intention, though, to use a double-tracked mainline? It seems like the second mainline track is unnecessary unless that is part of your greater layout scheme. Also, the runaround track on the lower right doesn't seem to serve much purpose other than allowing a switcher to run around a couple of cars and go back in the other direction--which, given the small number of cars one could run around, seems like it could be done more easily by just backing up the train.
The industrial switching areas seem to be accessible only by the second track of the interchange yard--trains would, I assume, enter on the foreground mainline at lower right, enter that second track and then back into the industrial spurs to spot cars on the facing-point spurs (2-5) and then finally run around the cars destined for 1.
My own personal suggestion would be to combine the two runaround tracks into one--essentially, one big runaround that stretches from the lower right, around the double-track curve, and then ends just before the entrance to the interchange yard. That would simplify things a bit, and give you enough room to run around a much bigger train--and save you the cost of two switches!
