Good progress so far. I guess I'll weigh in now...
Title:- The Title could be slightly bigger, maybe by 30%. It's also too plain for a header, personally I'd play around with giving it some glow rather than outlining. (You can add an outer glow from the Layer Styles) I'd try a glow that gradients from White to Red, so that you get a nice soft "power glow" of white at first, then it fades out to red...and softly falls off to transparent/black.
- I can see you're using the Font "bending" transform quite a bit here. At the moment the text looks too deformed, I would play around with the font's horizontal and vertical skewing so that the letters look less leaned over, and stays square perpendicular to the curve of the bottom of the letters. Imagine there's a line being drawn that follows the bottom of the letters, now imagine a line running perpendicular for each letter, from that curve and have your letters stay squared-up from that. It will help make the letters look more solid, while still retaining your curved layout.
- Line Spacing: If you're going to try to enlarge the title, I'd make the symbol under the Messatsu get closer to the font so that you can maximize the sizing space. On Marquees, it's usually a good rule-of-thumb for the title to be legible from a 15 foot distance. Traditionally marquees were designed not only to show the title of a machine, but also to catch attention and draw people in.
- Seeing that the secondary image behind Akuma is faded out, it's alright to overlap the Title Font. That way you can center the title font a bit more (doesn't need to be perfect), so that image feels more balanced. I'm not talking about complete symmetry, just balancing the "weight" of the image so that there is an even level of visuals going from right to left.
Imagery:- The Akuma side looks good, but it makes the Evil Ryu side look too plain. Mainly because you have a secondary faded image behind Akuma, but nothing behind Ryu. I'd try to add something behind Ryu, either another Ryu image, or perhaps some of that red wispy power smoke stuff when Ryu does his Red Fireball (or when Akuma teleports). Or how about the wispy stuff, PLUS a larger close-up of Ryu's face/head filling up the background.
- Ryu should be similar in size to Akuma...you could scale him up and have his non-existent knees start at the bottom of marquee, and have him fill up the space more just like Akuma's side.
- Colour-wise you've got pretty much a majority of Red and Black, which is cool and all, but I would add something more to the image to vary up the contrast a bit.
I suggest trying to put some of that Cracked Concrete background of the CP into the background of the marquee...perhaps as a background border frame going around the edges. Heck, you could even just have it go along the Top and Sides only, like an upside down U...or visa-versa Bottom and Sides.
