I think there are many little issues that you could easily fix, and then it would be a nice little animation.
- Why does his face move more down than the rest of the head? And his neck moves up?
- Then you have that awkward blinking pixels on his horn thingy.
- His foot behind is fater than the front one, which is utterly illogical.
- The bending knee could use a frame or two more. A little movement in the arms then would be cool too.
- The tail animation is smooth, but you could extend it further towards the back.
These are the things I noticed... I've been scrolling past this fellow several times, and it always bothered me to see it rotting in the public queue. I think if you rework it, it will easily pass, because the design of the dino is cute, and all the mistakes are minor: but summed up they make a slightly horrible showcase of "do-not's".
ty for the critique i improved it more and resubmitted now its out the queue
