Looks gorgeous and I like the ochre colors you chose. Aren't the eyes a bit too close together?

I like the animation of the shield.

I can't believe you made a whole series!

This one is very dynamic.

Like n0mzat, I'd like to see her animated.

Please consider dropping the flesh color in the upper part of her tail in the front views. At a glance, it looks like she has a penis.

I like her haircut.

The height of her lower back varies in the last frames.

Keep up the good work.

Very ominous.

That beast is the stuff of nightmares. The red feathers are a bit strange.

Very cool effect with th blue light.

Her posture is nice too. I just had a hard time reading her right hand at first.

Heartwarming.

I'm a bit puzzled by the perspective:

The black circle, the round patch of grass and the shape of the bushes seem to indicate a fisheye effect.

Yet the non-deformed characters and horizontal clouds go against it.

Nice. 

The style is so different from the games that the connection wasn't immediately apparent for me. The broken arches read like TV screens at first. What sells it as a Castlevania tribute is mostly the yellow-orangish character in front of a dark blue background.

Nice.

Not an easy transitional piece. Is it Adam Ellis' mermaid on top?

Nice animation. She gives good Kiki/ Momodora vibes.

Gorgeous scenery.

Yet it won't feel the same when the palm trees are grazed by the sky cow

It would make a nice title screen. I love the moody 80s cityscapes (Streets of Rage, SNES Sim City...) although it's probably boring to draw.
