amasing

An ok start, but could use some work.
There really should be more variety of movement- boyfriend seems to only raise his arm and that's it.
Tankman especially needs more poses and frames in general, as he moves like he's being warped by the transform effect rather than doing anything on his own.

Likewise, the characters have multiple small errors like lines in places they shouldn't be and Boyfriend being weirdly orange.

The part where you used the actual sprites did not do you any favors.
Not only did the zoom in on Tankman cause it to become extremely blurry, but it called attention to the above issues, as well as inconsistencies in the designs you made for the characters, especially Boyfriend.
I hadn't even noticed his bangs were the wrong shape until you threw up one of his actual sprites, at which point it became very noticeable.
Further, it's just kind of lazy looking- especially when the same characters could have been drawn standing still in one shot fairly easily.

My advice would be to take a closer look at the Tankman and Boyfriend assets, especially the sprite sheets.

Not only would these be a good reference to keep them looking on model, but looking at the individual frames on these sheets could help give you a better idea of how to pose and animate these -and other- characters in a more interesting way.

Also, if you need to zoom in on an image, either use one with a very high dpi, start out with a much larger image than you need, or use a vector.
Low quality raster images do not like being zoomed in on. ^ ^;

this is honestly just bad, like, why do I want to watch the same 6 different frames repeated for a minute
