Little Rubber Guys forums is the first painted Rise of the Beasts shots of an early prototype from the factory. Oddly (and refreshingly) the rep for the line actually points out some of the flaws and proportions, with things like this:
"Note: These are the first pics of the sample sculpt. Not final at all.
Also, this is the original factory that we already paid for this order.
Not the current factory that we are working out specifics with."
