I was really impressed with the amount of work they got done in such a short time span. I'd been a bit concerned about how each challenge could improve on the one before it, but the contestants really stepped up their game. Jake was the right one to go. His sculpt was only marginally better than Melissa's, and everything else on Melissa's seemed better. Ben's and Robert's creatures were both fantastic.
For some reason, I think it'll come down to Robert or Melissa. I think Ben has more skills than Melissa at this point, but she's shown how capable she is of learning quickly. And both Robert and Melissa seem really comfortable with the people that could be their bosses. Ben still seems ill-at-ease.
From the previews for next week, it looks like Brian will have more input into the design process or meet with the contestants individually or something. I'm looking forward to that, as every week he offers really helpful tips after-the-fact. If there's a second season, I'd much rather he be in the mentor role and have a rotating cast of judges.
