Thank you, superquad7. You're too kind. Next one is better. I just have to add some layers of yellow (I have already applied 6 hands, cover the black is a pain).
I add new stickers to my old Blackout. The little Scorponok and gun are the same. Desert Blackout is new, I give him a big bomb because he has lost his mini Scorpy. The sticker on the bomb says "Extra weapon system".
