This is the old Ariadna Scout Sniper model, but could certainly be used as the Ojótnik load-out as well.
The blues were painted with P3 Cygnar Blue Base, then highlighted with Cygnar Blue Highlight <> VGC Ice Blue <> White. Shades were added with VMC 050 Dark Prussian Blue (lining was also done with this) and P3 Coal Black.
For the camoflage, I first completely shaded and highlighted the blue cloth as described above. I then added rectangular patterns with VGC Cold Grey, White, and Black. The Cold Grey sections got some highlighting with Stonewall Grey and the Black were highlighted with VMC Dark Grey 166. The white provided its own highlighted by adding the second coat to a smaller area than the first coat.
Then, to help make those panels of color seem more a part of the cloth, I applied shadows to the deep folds and creases with VMC Dark Prussian Blue 050 and P3 Coal Black. These are applied to the cloth as a whole, irrespective of where the colored panels might fall.
