I think some darker pink detail and lines in the pigs would help. Right now at first glance it;s hard to tell what they are. Love the idea and everything is looking great.
looking great, feel like the pig could do with a very thin outline, make them stand out a bit, or take the rest of the outlines down to a slightly lighter shade.

The art is great as always, but in truth the concept isn't really anywhere near your best stuff.

Just writing out my brains out, verbatim.
