Messerschmitt Bf 109F-2

Here is a Bf 109, I wanted to make an F2, and used F2 decals, but I really didn't look to see what the differences between the K4 and F2 were, didn't think about it at the time. Looking at diagrams though, there were some major differences between the two. Been finished for a couple of years now, I am going to do another one, and on the next one make sure the version is correct. I am no beginner, but sometimes Im really a noob.
