Animals? Animals!

In preparation for developing some new characters for Professor Alpaca to interact with, I've been practicing drawing animals! So far I've looked at pigs, goats, and donkeys, and have early designs for the pig and goat characters. Here is the Professor beside two of his pupils:

They are supposed to be... in... scale... to one another (what am I trying to saaaaaay). I'm not sure how big goats/pigs/alpacas are compared to each another, so more research is needed there. The unnamed goat and pig are likely to change a bit. Also Professor Alpaca is getting more fluff on his face, which almost looks like sideburns. Heeee.
