Well in this case it is very easy to make a good animation with this character.
But there is a little bit of work to do before you start in moho.
In MoH you could go to MP with a friend or so and then screenshot him from different perspectives (with grenade selected or anything, a one-hand-weapon (Sidearm?) is better to animate later).
So within a couple of minutes you will have the neccessary different angles of that character.
Now what i would do (if you havent gambled with that idea yet) is to split the different limbs in a graphics editing program such as corel draw, photoshop or the very good and efficient free tool G.I.M.P.
So all in all you will then have arms legs, heads, etc. from different angles.
Then i would recreate the character in moho.
If your setup is clever, you can make every limb turn to another angle if you wish so.
Don't know if that was what you expected as suggestions, maybe it helps
EDIT: As i took a closer view on your screenshot, you already set up the character, so i just wonder what you want to know exactly
