My 5 year old son’s Lego builds

In the last year or so, my 5 year old son has really taken to Lego, and as someone who has aphantasia and incredibly poor spatial skills, the whole concept of building Lego, especially MOCs, is way outside my wheelhouse so I don’t really have a frame of reference for how skilled he actually is The first picture is his build from set 31377 using the instructions which he asked me to time to see how long it would take to build (14 minutes) and the second is his own MOC of Roberto from Futurama...
