They are good, but you lack soem things...
for one, they are fairly simple. This isn't a bad thing since we all need the basics, but tbh, they are going to be repetitive and boring if you don't incorperate more to them.
They lack physics.
Your kick test (bottom one) he jumps, stays in the air for a few frams on one spot, kicks, then puts his foot down and falls, now, im no expert and taht you can appreciate, but... Physics would say you cannot float :|, however, the movements are really good, so you have taht. your easing is ok, but very generic. maybe try working on how you would love to animate, rather tahn how everyone else does!
good job however, won't be long until you are intermediate.
