Your work looks really great, but I would adjust the scale on the art for the sides of the head and take the "Williams" off. As a retheme, it's not really a Williams game anymore so the "Williams" seems out of place. And for the art, I get that you want the bursting through the paper thing to show, but I think it's more important to have your art fill the side of the head more for a better sense of visual impact.

I made a quick example to show you what I mean using the art you posted earlier. Your original is on top, adjusted head art on the bottom.

There also were never anywhere near the number of colors you're using now in the art in the screened cabinet art they did back then. Usually it was only 3 or 4 screened colors. I feel that if you're limiting yourself to keep it 100% faithful to what was from that era, you've already broken that by using so many colors in the art (and it's an improvement!). So why stick to one other aspect of production when faithfulness is already out the window?

On top of that in your mockup the logo wouldn't be readably due to the keylock hole.
It is still the same game Williams made, so I want to make it look official. I may not sell/ mass-produce that thing or any decals anyway.

I completely forgot about the side-lock key on those machines. With a little adjustment of the art, it could still work.

Whatever you end up doing, looking forward to seeing the finished result. Your art is very good.
