Of course it's blue looking, I'm not disagreeing for the sake of disagreement itself. (technically the sky isn't blue, it's colourless, the blue colour comes from the light being bounced and bent inside it)

I'm just saying that some people are faster than you'd expect with no loss of quality and that non-artist customers don't tend to focus on anatomy as much as artists do so don't tend to notice things that are off as much as an artist customer would. Spending a lot of time thinking about something or seeing something tends to make people hyper-sensitive to when it's done wrong.

I don't know what your problem is but I bet it's something long and hard to pronounce.
