1:72 Mistercraft AH-1G HueyCobra-training model

Hi, my name is Patryk, I am modeller from Poland and now presenting my first model after 3 year non modelling period. It's AH-1G in 3 colour camouflage (which was used mostly in later AH-1 versions, but in Vietnam US Army had also couple Cobras called "Calico" Cobra and they were painted in 3 colours).
I aibrushed this set by Humbrol enamels, put on it gloss and matt cote from humbrol and for decals i used 2 gunze decal fluids. For kit decals it wasn't so succesful as for the "United States Army" sign, which was taken from Hobbyboss set. At the end i used vallejo Sienna natural pigment.
Tasks which i wanted to accomplish were:
a ) airbrush triplecolour camouflage , unfortunately i am not to happy with this (Humbrol 105 which was suggested by many people as dedicated as marines green, is too bright, passes between different colours don't look as i want :(/> Next time i will use pattafix and masking tape.
b ) good tape masking, sometimes paint got under tape, and i think i put in some places to many layers of paint, so i got "steps" after taking the tape off,
c ) cut canopy to made model with open doors, i got some break ups beacause i used scalpel, when i changed it to razor blade i could cut with out breaks on clean parts
d ) made this this clean as i can-you can see what i got, too much paint and pigment
My succes it definately painting gun and grenade launcher by myself
Now I am going to nuclear bunker and waiting for critic.
