I lengthened the goblin's sword; now it looks better.
The goblin and the scout have similar body proportions; I think it would be better to make the gnoll mage based on the goblin mage.
The goblin is a special creature in terms of animations; all three goblins have different attack, movement, and idle animations, so you can create three different monsters based on them, without considering the goblin on the tower.
If anyone is against this, please suggest your own options.
The lizards look cool. Regarding the gnoll shaman, I want to remind you of the idea of using the orc shamaness animation for the shamaness. The animations are quite suitable, wild, predatory, and feminine.
