There is SOOOO much the hobby has to offer. It is up to the individual modeler to explore new techniques and improve on skills. The one thing I always tell people is to practice and experiment on older or scrap models to find what works best for you. One thing to keep in mind is that the painting and weathering is NOT a by the numbers thing. I don't believe 'first this then that etc'. Every modeler has his or her own style and skill level. What works for me may not work for you so by me saying do this or that might not give you the same results.
The techniques are there for every one to use, and if it's not your thing then that is good too. The most important thing is to enjoy the hobby, learn from others ( and yourself) share what you know....but most important is to have fun. After 35 years of sniffing glue I am still learning with each model.....and having fun too.
