First, you have a beautiful family. Second, Your paint jobs look great. I have to really give applause to your freehand markings. It’s true decals are cleaner and sharper but I my self have used none on anything I’ve painted and I’m developing a way to layer and paint my own markings (It’s been holding up my project severely) I simply can’t afford to buy sheets of decals that I might only use a handful of.
One tip That I’ve adopted, is to use ultra-fine Sharpie permanent markers for small lines and details where a brush won’t do or may slop (canopy frames). Lastly I’ve learned from table-top gamers of much larger scale (Warhammer, Bolt Action) models that at the scale Axis & Allies models are you can “mass paint” with fewer details on many units to create large armies, fleets and air forces that will look phenomenal from eye level to table top . Anyway us A&A painters have our work cut out for ourselves. I salute you sir.
Anyway, keep on painting, Nice work.
