The above is something I followed a little while back... I added 20lbs doing this, I don't think it's so different from most splits but what I really took note of for it was the sets... It's still pretty high volume, but not compared to your split.
I really think your split is overkill. You could probably benefit from taking a larger focus on your main lifts and using the rest as accessory lifts.
