My HQ-compatible bad guys

Here are some Reaper Bones orcs and goblins I have been painting up.

The orc miniatures are not my favorite. I attempted to speed paint them and it shows.
They're missing contrast and I am open to any tips to fix them up.

I spent much more time on the orc bosses and am quite happy with them.

Also, I am very happy with how the goblins turned out as well.

Start with washing them brown all over and let that dry for an hour or two. Then wash the metals with black, maybe a touch of blue mixed in. Only a touch.
Then clean up the skin with the basecoat green, leaving the shadow areas brown/brownish green; then highlight as far up as you want to, but in tiny steps. Use yellow or a flesh color to lighten the green up. One or two highlights, basecoat, and the two shades a wash naturally provides in one go might already be enough for your requirements. YOu can go all the way to light reflexes in the pure color you mixed into the green, if you want to, in a layering fashion with zenithal lighting.

Same thing here. Highlights seem to be more "necessary" than shadows with the bosses, but just a few more carefully lightened up layers would really push it up - if you want to put in the effort, that is.

The goblins could also use more highlighting. Mix it up here, to differentiate them from the Orcs, by mixing in a light blue or gray into the basecoat green, but don't end in a purely blue color.
Myself, I don't like Orcs and Goblins to look similar in skin color. It makes no sense to me as someone who paints for the fun of it, but that might be different to you altogether.
My Orcs are light olive green with highlights going into yellow/beige and shadows tending towards purples and redbrowns; my Goblins are turquoise with blue/violet noses.

I understand you're mostly happy with your paintjobs, and that is all that matters. But if you wanna take it to the next level, more contrast, in tiny little steps into both light and dark is in order.
So far, well done, thumbs up.

Appreciate the tips, knightcrawler!

Have you ever tried Quickshade? The pots of varnich, not the inks. Works miracles. You shake the tin, apply with a brush, let it slowly ooze down the model into all the recesses, remove the excess with your brush, let it dry for 24h or more, than LIGHTLY spray with army painter anti-shine varnish. Works great, especially for masses like the orcs and goblins.
