I like the original backglass. The custom one is cool... But, for the nintendo Castlevania game. I don't think it fits the pinball table. Unless you got simon belmont on the playfield.
I mean... It would be great to have all pinball backglasses resemble A frazetta painting... But, there is only one Paragon. And yeah... I think the artist was totally aiming to rip off frazetta, as that game came out around the height of Franks popularity.
Back to the original topic. I think the original is good. The main thing is the colors... The color pallete is a bit weird, but maybe due to the printing that they had to use at the time. Otherwise the framing of it, and the body language, and weight, all are done fine. Nice sense of drama as well. Just weird color choices. If done in a modern style it would work. But, again I like the cheese and old school VAULT OF HORROR EC comics vibe... And yes... I know I put comics at the end of EC. And so that means I said comics comics... But, I wanted to make sure you knew what I meant.
But, I am a weirdo who likes cheesy things. I love the backglasses for Raven, Hardbody and other pins of their ilk.
