Again, same thing I said to david...
The letter fonts are not quite right.
You see, painting is easy...just get the right colors and swoosh, the software washes whatever part of the fuselage you selected. But for the letter fonts you need to have a complete sets of fonts or research hard for the right one. This is the most difficult part in paintings.

Most paints fail at these in some way and that is what first strikes out.
If you didnt fly in Northwest in the 70s, if you are painting just based on photos you saw, then it doesnt affects you.

But if you were alive and travelling in 707s in the 70s you realise such details as fonts...is so important. Otherwise the paint is excellent. Thanks.
