Hi, Nikola, welcome back to the hobby and welcome to the forum!
This is only your second airbrush effort? It looks pretty good. I like your base colors, and the variations you have on the blue gray upper surfaces. It looks like you have a good grasp on mixing and applying the colors.
I like, too, that you haven't overdone the panel lines and other recessed detail. I know it's a popular style, but all too often, such detail is overdone, in my opinion, and doesn't look natural.
I look forward to seeing more of your builds!
Best regards,
Brad
