You need to thin the paint more, decrease pressure, and work closer to your surface. Keep experimenting. Good luck

Check your the tip of your needle, you could be getting dried paint built up on it. Use a q-tip with thinner on it to keep it cleaned off.

With Vallejo Air series you should go for less pressure, even as low as 10psi if your compressor can handle this. Also removing the crown/swirl ring (nr. 1 part in the exploded view of your airbrush) will reduce overspray, watch the needle tip though. Also adding a drop of clear gloss might reduce overspray as well. Spraying from a shorter distance (a few centimeters) helps too. Grab a plastic lid of a coffee box or something to practice the settings.

I can't talk about Vallejo paints because I use Tamiya and Mr Color paints, but I do thin them a lot for detail work.. 75% thinner to 25% paint (3:1).

One trick which I learned from one of the guys here is to remove the crown and get REALLY close to the surface (but you need to be very careful with the needle tip).. and I usually have my compressor at about 10 psi or a little less when I do cammo and things like that.

Here is a sample I did using an Iwata Revolution which has a 0.5mm nozzle, so it's not intended for detail work.

I did the brown on the turret freehand... would you consider it to be acceptable?

for that sort of pattern, I've used the "silly putty" technique. Do a base coat of the lighter color, then put globs of putty where you want to keep that color, the spray the second, third or more colors using the same technique.

There is no "right" pattern, so it's very forgiving.

Came out very nicely in my opinion. Anxious to see it worn and weathered. Good luck.

It came out really nice.. I don't think you can really get zero over-spray when you do it freehand.. The washes and weathering will take care of whatever over-spray you may think is more than you wanted.
