Outstanding work Santiago! One more thing that really helps complete the realism is laser cut flush window inserts. I think they were from Chooch (might have been Tichy?). I haven't seen them in a while but I did put a set on a SOO SW1200 (that I ended up trading for a TH&B or I'd post a pic). It made a huge difference to the "thin-wall look" of the cab.
Keep up the excellent work - you are an inspiration to me.
