Hmm...
Did you round the top points of the thighs?
They look more like an old GF or TE...
The left sniper knee plate looks very off.
And the helmet looks very soft to be RS...
Very curious...
Could be the camera?
I have several castings. None are QUITE RS level of sharpness and detail... But yours looks less sharp than any of mine.
It's either the camera, or not really RS.
I hope we're wrong brother!
You do look good!
But at the very least... Trim the eyes out more, and extend the grey frown.
If you rounded the thigh top points... You shouldn't have.
