Hey Souly, I'm loving this so far! such a ridiculously awesome amount of style to these things!
Did a quick Edit on the female goblin, (I know I broke the style a tad.)

You basically just need to pay more attention to the breasts, hips, shoulders and thighs and accentuate these things appropriately. the rest of the body you can pretty much leave the same.
Evil Shroom is defiantly my favorite so far. Keep it up!
