In general I think your movement could use a little more easing. For example, the uppercut seemed a bit abrupt and I don't feel that it flowed into the next punch well. Perhaps additional frames and a motion that is more follow-through like rather than a snap-back. I think your second animation had better flow than your first though. Looked nice.
There is supposed to be a couple of enemies thats why the flow is a bit off.. But ill take the more easing part into account and hopefully do these daily ^^
