Thank you for the full body leg shot. 
shows the true size of the legs
a close up of the quads makes them look bigger than they really are because the pic gets filled up as much horizontally as vertically
but from full body shot the length of the complete leg provides context to size up the size of the muscles
the same goes for full body shots in general
this is why ppl always post close ups looking freaky
but you wouldnt notice them walking down the street
trust me i'm a bodybuilding analyst
