For someone who hasn't drawn them too often previously, you've really got a knack for drawing Goblins. Just a fantastic interpretation of ol' Kingsley (presumably). The expression is spot on, the pose is fantastic for how small his square is, and the slight design tweaks really make the design all your own. I definitely see some of Phil's iteration bleeding in here, especially with the ear holes and extra pouch on the belt. Nice touches. Outside of that, I am over the moon you chose Kamen Rider W as the wildcard character. Hell yeah. It was my first Rider show after a friend recommended it to me and it is just SO good. You captured W really well, super slick rendering.
Congrats on 800 followers, I'm sure you'll be at the next milestone sooner than you know it!
