1) removed the newly-added upper flap demarcation
2) made the underside weathering asymmetrical on the flaps by redoing one side by hand and shifting some elements in/out a bit.
3) reduced panel lines and slightly reduced the opacity levels on my BMF effect.
Please let me know if you like this or the previous BMF effect better. I thought it might be a bit too much (a bit too bright) in the previous screenshots.
