photo is big enough when i click on it, but for the future: use a uniform background, it will help.
thatīs your forst squad, so of cause there are something to improve:
first of all: yep, unfortunatley they are a bit sloppy ( not meant as an offense, honestly ), since i can see red color where it shouldnīt be.
Next time , take your time, itīs not a race. drill your barrels. read the artcle section.
For starters i would highly recommend you concentrate on clean painting and solid base colors ( yours look uneven ). Once you get that try basic highlighting and shading. No Dry brushing , though - that technique is just messy and wonīt improve your painting.
Also , white and red arenīt easy colors to paint - ask anyone.
You might wanna use the new GW foundation clors, theyīre great for flat base colors.
ok i hope thatīs helpful
