Ah~ I have to say I really love how you're giving each of the Kimono Girls unique designs based on the Johto legendaries; it's an idea I haven't seen before, but it fits them so perfectly c: They all look great~
I love the idea of basing all the Kimono girls after legendaries. So creative! And you're designing all them so well! I love them all! (I hope you don't mind if I just commented here and favorite all of them. )
I love the Legendary Beast/Lugia and Ho-Oh designs you gave the Kimono girls! But...I just realized something. If Zuki's the leader (per se), then shouldn't she have the Ho-Oh dress? You are playing HeartGold, after all.
My only complaint with this one is the head piece. Suicune's 'crown' (we'll call it) is sooo long, and obviouly wouldn't suit her head, but shortening it doesn't look all that' right. The proportions suit the others, but unless you can figure something else out, I'd suggest making their head-pieces less literal... as that enters the derpy territory of design. >.>;
Perhaps the 'horns' of suicunes crest could start beneath her hair and come out the sides, and then the hollow center of the crystal be where her head is, so that the crystal comes to it's point above her head, similar to a tiara (only it sorta wraps around the head?)
But anyway, aside from my nit-picky comments, I love these designs! Though I might suggest giving miki white hair. I understand the use of brown, but the overwhelming brown seems... well... overwhelming. Plus, since it's a different shade... I find it a bit distracting. :1
