Welcome Wild Dog,
Don't get discouraged by what you see other modelers doing! You will find that you NEVER stop finding new and better ways of doing a particular task. And every model that you build will have something that you look at and feel that you could have done it better.
I have been building models since I was 5 (I'm 61 now) and I am still learning and trying new techniques, materials, and new supplies that are coming out on the market.
I think your 109E is coming out very nice, the 109 is one of my favorite airplanes to model with a million different colorful schemes to pick from.
The bottom line is to enjoy the hobby, building models of any kind is great mental therapy!
