You don't need any constructive criticism on your neutral looks, they're great. If you think Woodwinked washes you out, maybe stay away from browns and go for more taupe-y colours, like you did in the second look.
IMO, it all looks great, I think neutrals really suit you! As much as brights do
I liked the hair better red, too, but the brown makes you look more seductive (I always think that about brunettes *shrug*).
Also; the dress is hot as, but I can understand your trepidations. I hope you get the confidence to wear clothes like that, because you look great in them!
