Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Your robots have all been fantastic but I think your strongest aspects are weather effects and coloring.. That rainy steam punk really captures it all, very beautiful piece. :D
I fully support the feminine painter for CAP2's design though sock puppet and straight-jacket - mon get a close second. The idea of a ponytail/paintbrush combo really sparks my interests.
Scarecrow is pretty awesome, the ponytail painter looks a bit too much like Mienshao, while the straightjacket reminds me of chandelure... I definitely think Scarecrow is the way to go! :D
I still say ponytail painter is the way to go, but If you want the make sock puppet-mon look more grass type-ish you could try changing the puppet to look like it was made out of dead leaves/bark?
make it grass/ghost? that way it sorta like it was left lieng around on the ground for ages and when it was posessed by the ghost part it braught along some of the plants it was resting in or something =)
Yeah i definately need to make it look more grassy/leafy. I had this awesome doodle in school of the sockpuppet only instead of a sharky thing it was kinda like a deer with a fluffy tail. Sorry no pics of it yet :[ but i've got it on the backburner.
