Thanks Alcopop and Indigo.
The arms/bracers received in yesterday edit anyways to little love, I edited them and constructed some parts of them new - they are also consistent in terms of size now.
I also edited the values of the hands.
The other thing I did was to unify the overall shading, especially all seperated armor parts are now unified in terms of value and plane direction.
Well i could reduce the colors down to something like 50 if I really wanted to do that, however the max amount I want to have are 64, and colors in this sprite which are close were also mainly used in Creya's sprite - therefore the overall consistency is for me more important than the lowest palette amount possible.
I might go over it once I have more sprites and don't need to add more ramps any more, so that I will gain a better colorweb - but as you said Indigo, the usage of colors used is controlled.
edit: just had the feeling that some weird things were going on with the cast shadow and quickly edited it once more
Also added the latest step to the gif:
