Okay so I might not have put too much effort in modelling stuff around me but I had some fun with the pyramid.
A brick
A cargo container
A block of eraser

Also, for those wondering, the lighting went a little like this:
Other notes:
I saw in a YT vid once that for hard surface modelling one should always bevel the sharp-ish edges so they catch a nice reflection and are more realistic (as in real life sharp edges are not absolute perfectly sharp, thus the rendering engine picks it up 
), so I did just that.
