This is an amazing drawing I really like it. You're a pretty good artist. Though I do see some mistakes in this drawing as Valkyr has some what of a "thicker" build. She also has her shackles and neck brace. But beside that, this drawing is just amazing. I love everything about this frame and this drawing.
I like it better this way. The shackles are something that really destroys the ingame design for me. Are we really supposed to think the Tenno would keep 20 centimeter long metal bolts in her arm? Or even reproduce them when creating a general Warframe based on her changed form?
They look good for an escape scene, so i can understand why you like them more, but for a Warframe that is send back in action they bite.
I'm looking forward to get the alt helmet exactly for that reason, to get rid of the neck shackle. But it seems the arm restrains are sadly there to stay.
