Eh, it lacks readability, as it is very monochrome. You can use some shades so it doesn't look like a paper and has actual volume.

Also, I don't really know why, but people around here don't like backgrounds if they aren't necessary.

 It took me A LOT to discover it was seen from above.

 Seriously, try dithering the background.

I love the train and the bridge.

 This is TOO good

 Looks glitchy!

 In order to use dithering you have to use different patterns to make it look more gradient-ish. I don't know how to do this without erasing all dithering, but the mountains look transparent...

 Am I the only one seeing a plague doctor?

 Why hasn't anyone commented this yet?
This makes an awesome icon

 What's that black thing...?
Very cute animation.

This one, remember? There was another one later in the game.

They aren't that alike, but it's just the fact he faces every direction that it'd be possible to make him appear in one game of this style.

 This looks like those dragons in secret of evermore.

Thus is SO awesome.

 If you have a hard time doing hands, just look at your hands and copy. Or make a photo. That sure works for me.

 There is one and just one thing that bugs me, and it's the reflection on the water. No waves whatsoever, that's only seen in swimming pools...

Also, the mountains at the background. A little trick for making them irregular is to draw them with the other hand, as in if you're right handed, do it with your left hand and viceversa, so they end up all irregular. Then clean them.

I really like the sky and the palette, and the general scene. (:

 It ended up a lot cooler!

The eyes don't look statueish though (Assuming that's a statue and not a living thing) and the wings have a bit too much contrast in comp arison to the body of the woman.

I like how the dress ended up.

Someone pointed out the line that goes from the eye to the mouth (next to the nose) and now I can't unsee it and it really really bugs me. Tienes un estilo genial, Zeo.

 I think you used a tad bit much of banding (if this is the right word) instead of antialiasing. Also, I can't really tell where the light is coming from since HIS left arm is all darkened and his pants are kind of bright.

In order to prevent/fix this you should make a yellow dot where the light focus is and then proceed to highlight and darken slowly. That works for me.

I think it would get so much better if you used brighter brights and darker darks (i.e. more contrast!) and you made more parts of his body shinier, as he is a squid and squids are slimy and watery and water reflects light a lot.

Also if you're lost on what banding or antialias is, please refer to the forums or search some tutorials (There are hundreds) on how to do AA right.

I liked it, though. The sprite itself is cool!
