Looks good. . .
Only things that I see are:
Deadlifts are a must on back day. An effective back workout would be
Deads
Chins
Bent Rows/T-Bar
Seated Row/Machine. . .
You also need stiffs on leg day, you have enough time to recover before back day. They are awesome for the hamstrings. . .
Eliminate a shoulder exercise and add shrugs. . .
I would strongly encourage rest days into the mix, and not to lift 4 days in a row. . .
Just a few minor things. . .
