After only discovering KJ (The Knight) in the past month or so, the one thing that always draws me to his creations are the textures. The paint treatments he uses adds depth and warmth to each piece to take it beyond little pieces of ABS plastic and add life to the whole. The combo of the Si-Dan goggles and Series 3 ball cap are inspired.
I also really think that TLG needs to start making more short-sleeve shirts for minifigures. We need a third choice to go along with the long sleeve or muscle shirt options.
