It`s my next experience stage. When i decided to do this character, i didn`t think that i will finish it, Perhapse i didn`t finish render of that work but textures and model have done
It took 2 months , but not fully, with coffee breaks)
I used a large count of references for body, suit, few references for helmet. Face i did from my imagination and also used few pictures as example of anatomy
