Oo, the chimera is cool. Very well blended in terms of animal mixture. I'd say the snake might not be as well blended, but fur to scales is just very difficult, so that's too big a deal. The shading underneath is nicely done showing that there is indeed a light source somewhere, so that's also good. The basic structures of each animal are also very sound, so nice job there :)
The owl's coat seems a little..thick to me. By thick, I mean the lines are too chunky to smoothly fit together and mesh well. It looks like you were going for a more down feather look, rather than the contour, so if so, it's a younger owl. Not too important, but anatomical proportionality is something to think about, though I don't really think the look is all too different.
The owl has a nice shape, though, and the eyes are quite piercing, which I like. The variance in coat color looks good, showing where the different colors are, and I like the pronunciation of the beak. Makes it stand out, as it should since it's coming further out.
Also, it looks like the owl has a beard, and that makes me smile, so thank you :D
Love both of them and I hope to see more animals!
