The weld look very good to me.
I loke the look of the reinforcing rings on the girder's holes. It's as if they 
where stamped or riveted in place.
The stem looks somewhat metalic when in front of the white background, not when 
there is something visible trough the transparence. Maybe adding some refraction 
with an ior around that of water: ior 4/3

For the sss, maybe having a fade_color with a short fade_distance could help. 
Does using strum help?

EVERYTHING HAS A GENDER

You may not know this but many nonliving things have a gender...

An Hourglass is Female, because over time, the weight shifts to the bottom.
