That's a nice simple routine, pretty similar to mine actually. But I wouldn't work out 6 days a week, I hit it 4 times a week (5 at the most when I am feeling up to it) and find that pretty good for growth. I assume you are going pretty much til failure most sets using that amount of volume? How many sets are you doing? I find I get better growth for chest if I add a movement that stretches it like DB flies, but that's just my preference.
