Design-wise, everything about this game has been blowing me away... except the trainer. The female one's fine though but the male one just looks so dorky and way too young. Has to be that striped shirt lol.
Well, technically, the trainers are supposed to be young anyway. It seemed to me that May's ORAS design was younger than either her RS or her Emerald design, so maybe that's something they're going for now. Something about these two though, using Elio and Selene from the Battle Royal for the sake of discussion, seems to make them feel like they have a more...generic quality to them than the previous player characters did. Selene's hat, and maybe her bag, are the most distinguishing features between the two of them, and it seems like they would be easy to forget after passing them on the streets. The other characters have a sort of level of detail (Hilda, Nate), or style (Lucas, Serena) that shows that they are meant to be important characters, if not in their world, then to us as the players.
Elio and Selene, though, are quite plain looking compared to other characters, even to Hau and Lillie, who at least have detailed hair styles and clothing. There is a possible exception to this with Red and Leaf, but they manage to get by as being more iconic than generic, particularly in Red's case. Actually, I could kind of see Elio being a male version of Selene in the same way that Leaf comes of as a female version of Red, something that isn't really true of any other pair of player characters. It feels like there's a certain level of detail that's lost to Elio and Selene, and because of this, GF has made it feel like these two were meant to play the role of blank canvases, to an even higher degree than Calem and Serena did.
The ability to actually change our characters around, as has been shown to be allowed, will probably let us make up for them appearing to be so young, at least to a degree. As long as we're provided with a good selection of clothes and varied hair colors and styles, for the both of them, we should be able to make them seem older than they are. Honestly, we need event clothing, or the return of the medal system from BW2, but with superficial rewards that we can earn, and not just buy.
