Hey dude, sorry for the delay. I'll be on normally now.
So I wanted to ask you some things and just talk about your tat. I've been playing around with some stuff, as you can see below. My first response was that the individual pieces of your tattoo are great, but meshing them together gets kind of challenging, if that's more what you're looking for.
These are just rough designs, and the final tattoo will of course be black/white with nice lines and shape.
I hope you get some ideas from these pics, and decide whether you want just a single gas mask image or Pred head/skull (which arent very difficult to whip up) or a combination of the elements.
If they are mixed, would you want Predator head to appear to-scale with puny human gas mask? Pred heads are quite big... That's something you can work around, though, like on the left picture, you could balance out the big-ass Pred head with masks on either side, make it look nice and even.
Other things to think about:
The black/white space and the overall "shape" of the tattoo on your body. Do you want something symmetric? Asymmetric? Round? Square? This will be what people see when they get that first glimpse of it on your body, shape and composition/weight.
Another important question is what kind of gas mask? Older, single or double filter, etc...
I think that's all for now. Let me know, homie!
PS - Feel free to laugh at the image on the right of the gas mask with Predator head in it. I don't think that would work, but it does have a strange appeal, yeah?
