Here's a tip:

If you want to have Portraits that look almost identical to the ones in Brawl, download the Trophy Model of the character you want. Apply textures to it. Position the camera to be in the same position as the CSP. Make the backgdrop of 3DS Max green, take a screen shot, crop image out in Photoshop, remove green, resize to the proper size, then make the image the proper adjustments (Palette, magenta, etc.)

JuLz's CSPs.

We were pretty much doing this since BrawlBox was out.

I second this. A  detailed tutorial explaining this exact method should be made. I did the in-game snapshot method but I would rather have the nice looking original poses better. Anyone willing to do this?
