Good luck with your cosplay decisions, Drauska. If I can suggest anything (and you certainly don't have to take it), I'd just say cosplay to your body type. I know personally, I don't feel good about my cosplay if I have to compromise or know I won't be living up to the character, and you really only do yourself a disservice in cosplaying characters you feel don't fit you physically.
Anyway, just a bit of advice. There are characters of all shapes and sizes, and I personally know how it can be hard to find one that you feel connected to AND suits you physically, but (at least for me) it is such a benefit and boost to your final product if you can cosplay to your body type. Makes for a much better product.
But, anyway, shutting up now. *zips lips*
