James Howard. Everyone of us old folks who built models in the late 60s and 70s built the Monogram 1/48th Mustang in his markings. It was a right of passage
Looks pretty great.You still need to work on those lower vent slots on the belly. I still see essentially black rectangles for the radiator and oil cooler.Try to use a single pixel black line for the hole and then a subtle gradient to simulate the indentation.Like these vents from my 109E's:
Fade it out another 1/3 to 1/2 and that will do fine. Also remember to add it to your Normal map.
Another nifty trick with the Normal map is to add a white gradient to the door itself to make it appear cracked open a small degree.
Looks good Vraciu and the vent shading is a nice improvement. I'd suggest making the lines for the flap hinges and gear doors darker than the rest of the panel lines. These lines represent gaps in the structure rather than than panel overlaps and so should be more visible.
Looks good Vraciu
