A little bit of character design, as well as a concrete design for future human armor. To the top left is a general color design complete with a little bit of relevant info. The bottom left right to the middle is what Tatzl uses in combat, how the weapons are loaded and fired, etc.
 
To the right is an amusing piece demonstrating the protective power of the TDCG EPS. Assurance that this tatzlpony’s fellows don’t get hurt from any blast that occurs just a little bit too close for survival without it. Twilight does not appreciate this, however.
 
None of the designs I make under “Hoo-man Concept art” are in any way concrete. Things may be different when I actually put them in the story proper.
