Don't know how strict double posting is here, but I'll try this and see what happens.
Anywhoo. Wasn't being very productive yesterday, so I thought I'd have a go at this.

First up, Boktai Popeye. Had a hell of a time trying to find the games actual colours. Popeye's colour are taken straight off Django and the cowboy-like guy. Also done, because I wanted to limit the colour to what the Gameboy Advance uses. I also noticed that Popeye is pretty tall and lanky. He just fits the box limitations. It was hart do duplicate the Thick border and bright colour style without the whole thing looking ugly.

Little mock up shot. I manipulated a gameplay shot, reused the background to erase the status bars and used it to add more background below. that way, I could get both characters in there. Took more time than it needed to... but what the heck.
(Here's the original, I could only find a low quality shot though...

Don't know what style this is in. I guess I thought of those cartoon theemed games like Mickey Mania. I didn't limit colour eather. I've used all 15 here.
Had fun with this. Hope I can enter the next one.
