Hey gabo1991, I really appreciate your critiques !
Batman
I think you are right about the neck , now when i look back it seems too short to me also !
I also have to make a-symmetry to make it more alive and interesting, thanks for mention that !
I will add tomorrow more angles from the batman and other works so you are welcome to open my eyes again .
Fairy
I used this image of the Fairy Pin-Up as a reference to my model and her left hand also feel too boring or stiff .
I’m open to suggestion how to make it more appealing , i know that i don’t have to follow the reference 1 by 1 but in pose like that she have to support her upper body by lay down her hand on her leg .
About the weight , i agree with you about how the muscle and fat tissue should be lay in pose like that , i will do more research

Gorilla - i will definitely make an attempt with fiber mesh , i don’t have lots of experience with this feature but i’m always ready to try 
I also saw your webinar on Zbrush workshop a few months ago about fiber mesh and other features and i was amaze from your knowledge and the power of Zbrush from someone like you , it was truly inspire to see someone who know Zbrush from every angle and perspective.
I was recommend on your course in animation group on Facebook to my colleagues after i saw how much i can learn from you .
i hope i will have the time and money to join the next course .
Thanks again,
Arik
