Found a wonderful tool on FA a loooooong time ago by zhivagod, which allowed me to find out what I wanted Brisk to look like physique wise as well as colors! I ended up liking the neon blue + yellow look over the green and black due to the lively look and the matching effect to his personality!

Credits as listed above, but just to put them here again :
