if you ask me advice ( and believe me you don't want, no no no ... And it's no like you needed any, i just ... wanted to say this ! DAH ! xDDD ) i'll say a twin for her, in syberia variation ( white/grey color hair, blue/red color eyes ) would do the pair extremely well.
But forget my weird love for white haired chick who got red/blue eyes. I just wrote to say i LOOOOOOVE all this fluffyty fluff fluffiness !
Your line width variation and slightly muted colors are SO damn eyepleasing, I love it! She's adorable, but then again-- you probably hear that a lot. But her knees are just so fucking cute I CAN'T HELP REPEATING IT
