An old friend of mine is opening commissions so she can be able to eat and pay rent. See here.$20-30! This is pretty much a steal for the quality of her work. As well, while it may seem like she only draws a lot of dragons and similar, she is well versed in multiple critter anatomies :D See here, here and here (note that these aren't representational at what you'd get in terms of color, digital etc, just anatomy. They're a bit old too, so she's even better now :D).
