I'm giving you a one star because I don't believe this really deserves to be kept on the movie portal for all eternity because it lacks the quality and substance.
But I've got some advice:
This isn't really a character test. A character test would mean you drawing common motions and seeing how these characters may perform them to match their personalities on the screen instead of just in your head.
e.g. One of them is clearly timid so he may take quick small steps or a shaky walk for a basic walk cycle.
Also, although there isn't any color, to due a proper test you should aim for the full motion the character will perform in the final piece. This isn't an animatic, it's a test, you can't really see how they will look in the final if they move every 6th frame(unless that is the look you will be going for).
A great resource to take as an example is Ben Bocquelet's "Gumball 1min animation test" on his personal youtube channel. It doesn't much resemble the final show, but you can see in 1 minute how each character differs in look and personality by how they move and in what time intervals they move(e.g. gumball is irrational, so his movements are snappy and dramatic, while darwin is sensible and moves very steadily).
Hope that helps and good luck!
