This sketch of Robust from the 1st Gen SENTINELS was done by Matthew Fletcher. Matthew's art caught my eye as I walked around the Con and I was glad I decided to get a sketch from him. I gave him a copy of SENTINELS Book 4 and told him to pick who he wanted to draw and he chose Robust. I think that fit his style well. I really like Matthew's line work and think it's unique style. But don't take my opinion for it, check it out for yourself at http://www.mjfletcher.com/ .
