Nice character and linework !
I especially like the forearm tubes and shield and that knife on shoulderpad, neat !
That's just me, probably , but I don't feel the mask is really fitting to the silhouette overall...(or simply resize it ? a little bigger ?)
Maybe you could try other masks (and or species ? or whatever else)...
Also a very big hair on her back could look neat !
Just saying like that, if you don't want, don't force you to do anything I said !
I always like to help here and there...but I'm not sure if people appreciate ^^'
Anyways, good luck Fris !
