Yeah, the characters all have distinctive mane styles, so you can distinguish them even without colors. As far as I can tell, they all have the same features -- eye size, muzzle shape, etc. -- with a few exceptions (Rarity has five eye lashes instead of three, Applejack has freckles). I think -- I'm not sure -- they may all have different *expressions*, though. Applejack looking mad doesn't have the same expression, exactly, as Fluttershy looking mad. That may be a function of the characters having a range of emotions that's typical for each one, and that the type of 'angry' that Fluttershy gets is more stern, while Applejack is more simmering. It's hard to quantify, but I think you can almost recognize the characters by expression, and that's why my Dash looks like Twilight -- I didn't get her expression right. Even though she has lots of different expressions, the one I drew isn't one of them.
