Don't feel like the Lone Ranger. When someone has something pertinent to say, they will.
Your installation looks good, so far.
Fan Placement
If you put fans side by side, they just circulate some of the same warm air. You might consider putting them at the top and making them both pull air out. Place matching-size holes -- maybe with grilles over them to keep trash out -- as a point to pull air in. Hot air rises, so putting the fans at the top pulls it out in its natural flow pattern.
You could also put the grilles at the top and the fans at the bottom, pulling air into the plenum, but that works best if the plenum is pretty well sealed, other than the openings you placed. And those bottom fans that pull air in are more likely to get clogged with waste.
