Gary... I completely understand the Frustrations of "pleasing" someone else with work and I know it is important to decide that IF that is the endeavor, the adjustments are all part of the course.
I have to say that All of Your Previous Work is Not a Loss because it is built on what you have already done rather than starting over from scratch. These are "Adjustments" not Total Loss of Work. That may seem like trying to see the "Silver Lining In a Cloud" so to speak but True none the less.
Generally I do not post what I would otherwise do so in a Private Message or E-mail but you have told me that you prefer this so I am only stating what I see and that can improve your work efforts. Seriously, I am not trying to be TOO Particular... I know you want true opinions and I am just offering that
Be sure to Keep the Fun in your Efforts because Creativity NEEDS Fun or it is not inspirational and will lack that Fine touch that can only be accomplished through Inspirational Desire.
Just to make my point...your 1st Render would be better than the existing Game Unit for the Position so do not despairat all... I simple understood that you wanted Detailed Feedback.
This all reminds me of the Old Adage "No Pain, No Gain" of course that is easier to say than take

This Unit is coming along VERY well and will be a Great Unit indeed
