Thank you very much, 'Conceit' for the time you took to reply and for those nice comments...
The design of the robot is indeed mine but is based on several anime robots i've seen in my life... I don't know if i did well but i pixelated it right away without having made a sketch of it before... Maybe that would help...
Yes, i'm doing similar graphics for a turn-based strategy game i'd like to see completed sometime in my life... The point is i'm very new to pixel art so i don't know a lot of things and also there's alot of work that needs to be done... In side-scrolling, you only have two directions while in isometric you have four...
I've taken some animation courses and have done some flash animations (you can watch them here
http://www.mytoons.com/weaselpa). Most importantly though i'm an illustrator (with a 'deviantart' page here
http://weaselpa.deviantart.com/). So while i admit lacking certain amount of knowledge on animation, i'd like you to please point out in this piece what are the illustration principles that are not visible... Do you mean it's design or the lack of shading...? Since you mentioned it, i thought i should first finish all the animations and then proceed to shading as i think the black outline helps when you animate... As for pixel shading in general, i've shaded some static characters and an iso building...
As for the robot guy looking like dancing, i deliberately wanted him to have robot-like moves in order to save some frames in animation... Maybe the fact that the animation plays forever makes you have the impression of him dancing... Anyway, that's the reason i posted it here, so that people comment on it and advise me...
