I can't seem to make any rhyme or reason out of the groupings of your days? You're not doing upper/lower, but you aren't doing whole body either. I also don't see any groupings by push/pull or vertical/horizontal.
Day 1 you have heavy lower body but then at the end you throw in a bunch of miscellaneous upper body movements
Day 2 you have 3 presses, 2 pulls and calves and abs
Day 3 you have cleans followed by some arms stuff, leg extensions and push jerk
Day 4 - 3 pressing movements, 1 pull, 2 exercises for triceps and then calves and abs
So just on the face of things you have almost double the amount of pressing to pulling which can end up being an issue when usually most people would benefit from the opposite ratio.
Some good programs that have the flexibility you are looking for might be either either 5/3/1 by Jim Wendler or the West Side for Skinny Bastards by Joe Defranco. Both of those programs have set guidelines but enough wiggle room between the guidelines also.
