P-51B Template messed up?

[ColTreize]

I managed to make a very slightly modified skin using the available template, but the tail, wings, and spinner are all wonky- parts misaligned, markings not lining up between upper and lower surfaces, portions of the file showing in the wrong place, and even parts made transparent. Is there a problem with the template?

Hello @ColTreize
That's the kind of work you'll see in many templates.
The P-51B template isn't bad, except for a small transparency error, and as I said, the work lies in placing all the parts correctly.
There are simpler templates that you can do quickly and others that can take days to finish the way you want.
In fact, I update many of them after publishing them when I see an error that I didn't notice when I made them.

The problem is probably due to GIMP's reluctency to accept advanced Photoshop-specific effects and text in a Photoshop .PSD file.
