Paintseagull, your #2 is so adorable it hurts a little (I think it's the big shiny eye), but if using that pose for the submission I'd be sure that the right arm is shifted a little, or the whole poke turned a bit more towards us, so that the waist and skirt aren't as obscured by the cannon.
CBMeadow, that last one looks very nice, particularly the texture, but the general pose of it looks stiff and awkward. In particular, you have fallen to the tragic mistake of a symmetrical arms out at sides pose. Stand like that, it's not comfortable, and rarely do those sort of neutral, symmetrical poses look natural or interesting. Aside from that, the head, I feel, is turned too far downward, like he was in the middle of staring at his navel and glanced upwards. Another pose of embirch with that same very nice coloring and texture would be something fantastic.
I'm going to see if I can get a foot in this race some time over Thanksgiving, be a shame to only have two submissions for such friendly little treecannon guys.
