Svyat's Spites (again)

[Joxon]

These look pretty good, but contrast is a great thing, my friend. The lightest blue is too close to the mid-tone blue, you can hardly even see it. I also think the skin tone could benefit from some hue shifting a bit more, maybe the red shade too.

(Just in case, straight from the sprinters dictionary)

Spoiler

HUESHIFT- Hue shift, as the name implies, is shifting the hue.

rather than increasing or decreasing a color's saturation, or its Contrast, you switch to the color to the right or the left on the colour wheel. Notice also that colors on the exact oposite of the colour wheel also work as a darker/lighter version of your color. A more dinamic and natural palette of colors is the result of a proper hueshift.
Note: HUESHIFTING can be combined(an to an extent, has to) with CONTRAST and SATURATION in order to produce a wider vaiery of results.
