Definite improvement on your Twi'lek's arms, they really stand out well on him. As for his skin tone, it is very rich, very vivid, and I like it! I think I see a bit of darkening shading on his tentacles, but perhaps a little more?
As for the 2nd figure, your Smuggler, his chest guard looks great, but his legs look way too skinny. He looks like he'll have a hard time getting around without falling on his face! His upper legs need to be bulked out more, maybe his stance widened.
Great updates!
