I like the idea with making the cactus as a balloon. Although I'm not sure about either #25 or #24. The font is OK but would prefer a rounder heavier font. I'm into getting a character that we can use in different ways later so try to work on that. But don't overdo it with the details.
Try to work more on height than width.
Keep it up, but these two goes into the not interested category, sorry.
#33 made me lean forward... Go easy on the pink. Like the wads, not sure how we can use them but it feels interesting as concept. This entry is playful, feels soft and friendly, which is what we're looking for. Font alright. Missing a little touch of the web 2.0-feeling with reflections etc. I understand you picked up my earlier comment about the balloon but this feels more like a balloon only and not a cactus balloon if you know what i mean...
