Thanks!
At the moment I wanted to focus on animation, thus I made her pretty small :D
Still waiting for her to stop taking pictures.....
Jokes aside tho; nice work, has lot's of character and movement for such a small size
Thank you, Manupix.
It seems that everyone is pointing at the same "too much colours" issue and, thanks to that link, I can see statistically why and where. That's an useful program, actually!
I'll try to post my next works on the forums to refine animation and stuff before actually posting it here, you all know your pixels very well.
Ty for the nice words, Finlal!
Yeah, I know I'm having problems with coloring (i'm more used to digital intuitive painting and illutration)
Thank you for the frame length advice, I'll try to apply it on next works ^^
Thanks for the advice, andrae, you're very kind.
I'm currently using GraphicsGale free to animate stuff!
I love the anim and posture. Very good start! 
What bothers me a bit is the stillness of her left leg and belly. Also agree about colors: you could cut that by half without noticeable effect (the 4 or 5 near-whites for instance), and likely go down to 8. I suggest trying it as practice =)
Animation is REALLY good for the first time. Looks very alive.
Only nitpicks - too many colors and arms on frame 1 are much longer than on frame 32.
Also, you can set timing for your animations to reduce number of frames and, as a result, size. For example, instead of having exactly similar first 10 frames 0.03 seconds long, you can have 1 frame 0.3 seconds long.
Smooth. Maybe change the color of the background to make the body visible.
What are you using to animate this?
Muy bueno!
Oye, cuál fue el programa ese qué te recomendaron, el link está muerto...
