Ok so here is a compare side by side and an overlay i did with the pic of my helmet i posted above and the "between shots" screen cap.

Now i didnt do this to inflate my ego or anything lol..i just honestly wanted to see how close it was to the visual i was seeing in that shot. The angles of the photos are very close which is why i decided to give it a whirl. I think my helmet looks pretty close, and i did add that 1/4" width to the bottom of the helmet. the ear platforms appear to have very similar angles.
As far as the overlay..well its not perfect... between the angle of the photo not being EXACTLY the same, and the size of the photo may be slightly off .......and well im sure the MR isnt exactly like the Hero. But i think my helmets achieve the look i was after, and that little bit of flare was added to them, which was my main point.

I did not modify the angles or anything of the likes on the DVH helmet when i did this overlay. I just scaled the pictures to match size as closely as possible and tilted it a bit to match the screen shot.
