by seeing ur animations i can clearly see that u are animal animator, and that is very difficult i can tell u, cuz they have all those motions, like u have to keep moving there tail at all times, u have to ease a lot so that the animation looks like it was a big dinosaur that u animated, or it will feel like it is just a small chick of a dino. an animal is not like a normal person, first u make one movement, then u ease, then make the next movement, until u are trying to actually try making a dino fight. even then u have to ease after one attack.
talking about ur animation, they lack almost al the basics. the feets arent fixed to the ground, the movements are shaky, the tail is stiff, the neck is stiff. there is spacing problem. if i take ur ovi anim, i dont understand what it tried to do in the start, if u want it to scream, u need to bring down the neck, the body, fold the legs a bit rather than keeping them stiff, make a long screaming motion of a up and down going head every frame [ i have my animations on my laptop, so i will add a clipping later on, if i remember, i made a man screaming, u could find that on my thread, it can tell u how to do it but i will try to make a screaming animation] and the arms will go back towards the torso, kinda like when a kid screams. after that when the dino or bird starts walking the legs arent fixed to the ground, use this method to fix that.
now if we look at the back of the dino u can see a very bumpy way of moving, thats not how a dino or a bird would walk, it should look smooth, the bumps will only be present when it lands its foot, that should be smooth too. ease the land, and start a new movement.
about the sticks, they are awesome. u could showcase them in the pivot chat or resource section and u might get some reviews, but even so it nice to look that ppl still want to create sticks by themselves. whereas ppl like me, unskilled or lazy go around asking for the sticks lol!
anyway, keep animating. these do look promising.
A tip, try actual stick animations, once or twice. u can reach higher with that, cuz that is a very easy way to learn some basics. u can try a tailed stickman for easy tests as well.
