You can add plenty of 'stuff' to the background here, but the primary issue with this draft is the static positions of your characters. It really stands contradictory as to what the movie and (specifically in this case) the pinball machine are about - frantic, dynamic, action. The original translite is terrible on multiple levels, but the core issue is the same; random, static images of characters that are mostly just looking around in different directions. Even the images that convey any motion here (a couple vehicles and Arnie on the crane) are so far removed from there their context that they appear static as well.

What is it specifically you do not like about the alternate? For me, it's really just the title font/placement that I have issues with. This title has no dynamic movement like the original, but other than that, it's actually pretty good at conveying the theme. Is it cheesy? Yes, but let's call a spade a spade here... It IS Last Action Hero we're talking about- not the Godfather. Let's break it down a bit:

The 3D effect of Arnold swinging out of the movie screen conveys a great sense of action and depth. Also, the shape of a movie screen is easily comparable to the shape of a pinball backbox, which help tie the two products together as a whole.

Unlike the original with the big creepy Arnold head and random everything else, everything here is designed to draw your attention to the main image. The giant explosion conveniently frames out the main characters (not only by use of space, but by using complimentary colors orange and blue (as a side note - search google images for orange/blue movie posters - you will be amazed how many use the orange/blue trick to grab your eye - especially action movies)). Addtionaly, almost all the background characters, including the dinosaur, are facing the main image which further draws your eye toward the center.

Speaking of the background, it's very packed and busy (like the movie (and the game)) but the colors are more muted and not as contrasting (no black outlines on the background characters) so it doesn't overpower your focal point. And again with more tried and true orange and blue.

Hmmm... I suggest you bring all the images up on your computer: the original, the alternate, the flintstones, and yours.

Categorize what it is (specifically) that you do not like about the ones you in fact do not like. Does your version fix those problems?

Categorize what it is (specifically) that you DO like about the ones you do like. Does your version include those characteristics?

I don't know your level of art/design skills, but please, please don't take any of my constructive criticism the wrong way. This is all part of helping you ultimately get what you are looking for. You are the one that has to look at it in the end- not anyone else. I think you are starting down the right path though- sometimes these things just take time to get right.

lol.

hassanchop makes excellent points, and his sketch is a great starting point.

Maybe her boobs could be bigger, have you thought about that yet?
