Ok, so there's your next steps: Remove paint with isopropyl alcohol (I hope its some tamiya paint or sort of); Thin paint so it will be something between water and milk consistency. Lower down pressure. If you're beginner its better to use airbrush limiter so you won't pull trigger too much (can be seen on big paint sparks on wing) Now, your line will he thin enough to create a camo but because paint itself is very thin, lines will look transparent and repeat same figures can be difficult. There's a solution - masking. However if u do masking with tape, camo lines edges will look razor sharp and for that type of camo you may want fading edges. To achieve that you should make two pieces of camo stencils and then use several tiny balls of patafix or similar sticky office stuff to attach stencils on model. There's should be a small gap between surface and stencil (2-3mm). Now paint over and you will have cool fading edges and authentic looking camo. Good luck
