Looks good so far!

I'm sure you just started these guys and if you need to add depth just let me know..
What would I do at this step--
(for the bearded/pink guy.)
-Jet pack all one color.. with minor detail colors. white rather than gold for that
-drybrush all the black areas with grey, then a black wash.
- I know these are cell phone pix so less detail but the gold rope ends look like bells. Either the paint is too thick or they just need a different process of paint...
-for gold-- base with gold/brown mix. then drybrush with the gold you used to mix previously. then drybrush after that with gold/silver mix. you'll like it
