Actually, one of the reasons why I like the original Littlefoot is because of his "stubborness". The sequels, in my opinion , turn Littlefoot into a bland goody-goody who is treated as if he was perfect. He is not perfect, but none of the characters are.  
It also seemed to me that in the original movie Littlefoot was the one to make all of the decisions because he was the only one with any idea of how possibly to get to the Great Valley.  He only has his mother's guidance, but the others had nothing at all.  I guess that they thought that it would be better to go off of what wisdom they had than to do nothing and die in the barren wastelands.

And also, it wasn't just Littlefoot who thought that Ducky would make good bait; they all looked at her when he suggested it.   :

I like the evil smirk on Tero's face in that group picture, and if you ever want to redo it I think that you should restage the picture so his face is the focal point    

Stygia is cute, but her right thigh is a little short.  That shade of orangey-yellow is a favorite of mine! It's also neat to see a more realistic flyer trio.  

Now I want to see that walrus and aspirin picture too; my curiosity has been piqued :blink:

Ooh, very unique coloring style!  What do you use to ink and paint with?
I guess I should also ask if you want constructive criticism on any of your art, because I won't if you don't want me to.  :^.^:

9/10

For using animation from the first movie.  

I honestly love the way Optie looks here! Love the way her tiny flippers are raised, love the angle of her face, she just looks adorable  :^.^:

About the rest of the picture:
I like the vast difference in size between Optie and Lio, it really emphasizes Optie's 'tininess'.  The shadows you've put under them are a nice touch.  They make it seem like the characters actually occupy their environment instead of just sticking on top of it.  
One thing though, I think Lio should be in the shadows more, with just a little bit of highlight on his back.  It would make him look like he's deeper underwater.  Unless they are in shallow water.  
How deep in the water are they? Seeing how bright they are it looks like they are close to the surface.  

I hope my crit is okay; I actually like this picture.  

You actually did a pretty good job with the coloring, especially with a touchpad!  And her head shape looks pretty spot on as well.  

Can I make a few constructive criticisms though?  
Her hind leg should have more definition to it, I think.  Right now it is kinda just straight up and down.  I also think that her eye should be more rounded instead of dome shaped.  

This is still a nice picture, and much better than you seem to think it is!  

Hello and welcome!   Glad to see another Don Bluth fan.

Hi there!   I like your avatar (I know that sounds kinda random)

Well, I don't really have any images in mind (other than the Statue of Liberty) but I think that for most people, the American Dream would mean to be successful and to have enough money to be able to live "comfortably".  Maybe an image to show new beginnings?  Like a sunrise?  

Have a happy starday!
