I'm going to analyze the pictures myself later, but I think you might have already hit on the things that I spotted. My first thought was...the PG sucks.
In the very first picture, the PG came too deep in the paint, then tried to pass out to the corner where it COULD be easily intercepted. If it was me, I would have shot the open mid-range or used a euro-step to force the big to foul me or jump too soon for the block which would left the big open for an uncontested layup/dunk.
2nd picture...without knowing if the offensive player was forced to pick up the ball, I'm going to assume he still have a live ball. I would use a triple threat move to make the defense react. More than likely, I would use the screen. If my teammates are good, the screener should swing to the other wing, and more than likely they would switch on the matchup. My build is pretty quick, so I'm going to be approaching your defender quickly. He's either going step up to try to prevent me from rounding the corner, or he might follow you into the deep corner. My gut instinct with the current meta...they can't resist a double team, so I'll just a backward dribble move to "bait" them into the double team attempt and hit you in the corner for the easy 3. DAMN...just looked at picture 3 while typing my response. Naw...your PG made a stupid pass.
I don't see any problems with Pictures 4 and 5. Either you can shoot the shot or make an extra pass for the corner 3.
