hey man, nice concepts, great shapes,
In the first post, we could see a spiky shoulder pad that hooked the gaze in the bust region, maybe it would be cool to keep it, as it attracts the eye to the upper part, and maybe add the skin tight turtleneck from the portraits too add contrast/interest to the face. For now the eye is mostly stuck on the legs.
And in terms of color, you have 4 tones, cyan, deep blue, grey/black and red which is almost too much, but it works, the only thing that bugs me is the orange light on the diaphragm, it gives it a little too much importance even though it's a tertiary color.
Hope it helps
