The title is pretty self explanatory, but I'll start off just in case there's any confusion.
Following my comment in the New Costume Pieces Request thread, I've been reminded of a couple of character concepts that I just cannot get to work.
My first is a living marble statue character. Using the brightest white as your primary colour and the darkest black as the secondary colour on the Spectrum costume option gives you a pretty much perfect statue effect.
I have a character name and backstory all made, but I just cannot get the costume right - given the character's name, it's pretty essential they wear a mask, but the Detail 1/2/3 options for the head just do not match what I see in my mind (a simple domino mask). It's so jarring that I just cannot bring myself to make the character proper.
I've also had an idea for a Tanker I've wanted to make for a while with a Pegasus theme that leans more toward the super-heroic than the Greco-Roman but, try as I might, I just cannot find seem to make a costume that satisfies me.
Finally, I've a character that I really want to be a War Mace/Dark Armor Scrapper, but every time I play them, it's just a deeply dissatisfying experience and it breaks my heart as I had intended them to be my main at one point.
How about you lot - what character concept could you not get to work?
