You could always do alternate character sets, like have a pack following consistent guidelines and also one more suited towards your own scene. That way you can appease scrutinous people like myself and another side of the community whom prefer alternate costumes more than the standard Brawl ones.

I generally stick with the more 'canon' costumes, like ones from actual game appearances or references to other characters in a series (such as the Fire Emblem representatives), so I'll probably be using something like the Conductor Link outfit myself. The only exceptions to this for me are characters like ROB, Ice Climbers, or the Trainer Pokermon which don't really have much canonically to choose from (aside from Charizard) which lends them to a bit more creativity costume wise... also Sonic, because who doesn't love Jet Set Radio?

If that's the case, I think you should consider changing Ness' eyes to be more exact to the other models, because there is definitely a significant difference there. I would also suggest keeping Ness' trademark hair puffs rather than Shin's spiky interpretation of Ninten's hair. For any other character it wouldn't really matter, but because Ninten and Ness share such similar designs those little details really matter. That consistency lends itself better to the understanding that this is a cosplay costume, similar to how Marth and Ike keep their general appearance in different attire.



That being said, I now really want a Lloyd costume for Lucas to match Ness - it's a great way to represent Mother 1 in a way that Brawl originally failed to do. I guess that also means Roy needs a 'cosplay' outfit as well, but I don't know who would be willing to take on these kind of projects at the moment.
