Hi,
If I can add my two cents...
Obviously, there are more experimented builders that I am, like the doog, disastermater, waynec, etc..etc..
I'm just about to hit a one year into the hobby in a serious way. I have already build a couple of tanks Im really proud of them, they might not win any award, besides my family and spouse with a "looks nice" kind of compliment.
I think you should not try to copy someone else finieshed "look" or technique, buy some cheap kits and basically go crazy with them, add them a lot of pigments, washes, etc.. so you can see what each one does.
Also, use top notch products, like in a food recipe, the greatest the ingredients the better it will come out. Some might say, buy cheap and they provide same results...it might be, but I want to know I will always have the same results = consistency on the behavior of the products.
Also, follow the suggestions and recommendations from the experienced guys, even if it took you a lot of time to achieve a look or finish. eg, my last build, I spent a well 3 to 4 hours trimming the "burned" tire then melting it, which I thought it was pretty cool, to be finally discarded, as it looked akward.
See this example... I went oil and pigment crazy, but I really liked how rusty and bandoned it looks like!
No one can say it is not that rusted or about to fall apart. I will take out the tires and rims and leave it the suspension on top of bricks...
What has also helped me a lot, has been to read a lot of books in building, magazines and also videos.
There are 1,000s of videos in you tube to achieve any look, weathering, techniques. Trust me, I learned a lot from them.
SO, go ahead, go crazy and just experiment, play....HAVE FUN!!
