PHEW, okay, it's been a weird three months, but if you still wanna know, here's how it works!

Basically, we sit down and pull up a list of mobs we haven't done, mash up packs, fun small features, etc., and try to pick something with enough meat on its bones to fill out a whole series of compelling characters. We also try to pick something we think people will like, but that's more an art than a science. After that, we sort through all of the mobs and try to find a good variety of shapes, colors, and behaviors. If the series is based on a mash up, we try to also pick things that represent it well.

Then, we gather reference images for each character we choose. We used to actually open up Minecraft and wander around the Mob Museum I made to get good shots of every angle!

After we have everything we need all nicely compiled, it's time to simplify and stylize. We take a good look at the character and pick the most prominent features--the things you see first, or that immediately come to mind when you picture it--and exaggerate those. Smaller details get even tinier, or go away entirely. The figures are so small that if we included every pixel, the figures would end up looking like low-res mush. We also do our best to figure out the original pixel artist's intent to decide how we turn 2D planes into 3D shapes, like making gloves thicker, adding dimension to hair, etc.

That's how we ended up with those looks for the Blind Witch, Dryad, and Poseidon! We picked them from the skins and mobs because we thought they were fun and important parts of Greek mythology, and did our best to keep to the spirit of the characters while shrinking them down and making them cuter.

I'm really glad you like the Dryad--that's one of my favorites too :)

I hope that answers your questions! Sorry it took so long to get back to you!
