Kommissar, I would recommend "washing" the helmet and armor. You seem to have done a great job with the individual battle marks but I think it lacks that atmospheric grittiness. In fact, that could be the "detail" you feel like you are missing.You've done a good job applying dirt and rust, now you just need to fill in the blank spots between them. That's where washing comes in.If you're unfamiliar with it, washing (commonly referred to as blackwashing) is when you take spray paint and mist an object from like 3-5 feet away.So what I would do is take some black, brown, and grey spray paint (maybe tan for a sandy touch), set the helmet down in a controlled enviornment without any wind (I used my garage floor with paper laid out) and spray the paint from 3-5 feet away. About shoulder height if the object is on the floor. Spray in a fairly large sweeping motion to get all over. The idea is to get a very fine mist on the surface of the object.It may be hard to notice at first, but if the paper around the floor is covered in a fine dust-like overspray, that is what you are looking for.Here is one of my helmets before and after washing it.It may be sort of hard to tell from the photographs because they are poorly lit and un-detailed. But in real life it adds a very gritty look akin to accumilated dirt and grime on a metal surface. It makes it look more real and can get rid of that "cartoonish" look.You may also want to look into other more unconventional methods of weathering, such as water stains.There's a lot to weathering besides battle marks. "Atmospheric" weathering as I like to call it, plays a big part in the overall look of a piece. It's one of my favorite things to do. Let me know if want any more pointers in this stuff. Keep it up!
