The artist uses a different technique, I do believe it's not grey lineart, it's black lineart that's a little weak. We're working on it :)
And CW standards are higher because revamping them is less of an option. Through staff we draw up so many thousands of items that sometimes a few will get through that are a bit 'different'. I like to let this happen on occasion to let different styles in a bit which does bring a bit of variety into the site wearables.
Sometimes it works, sometimes it doesn't! There have been so many things that I've done this with that I thought would get this reaction and they've ended up being very loved! Thanks for the feedback :)
