James--good work in your first foray into modern armor! As Frenchy pointed out, your build has some details wrong, but it is still a good effort. I like the weathering of the stowage items, but you may want to add a strap (or more) to the items on the top of the turret. In addition, I can't be sure, but it looks like your tank has the old tracks, not the newer block-style ones used since the 1990s. You also painted the backpacks and covers with the older chocolate chip cammo pattern that was phased out soon after the first Gulf War in favor of a three-tone desert pattern. Was your base kit one of Dragon's or Tamiya's older Abrams kits? I think that may be the reason for the detail errors.
In addition, I think you left out the towing ring on the bottom of the center engine grill in the rear.
