Comic Test

Just some testing on a panel for a, uh let's say test comic, so this won't make any sense to you until you see the rest of it but yes, they're on a shooting range for some target practice until Maika gets in and has nothing better to do than... Ah, you'll see it later.
I will move it to scraps later, but now I need your help by telling me if it's all ok. Less details? No shading? Bigger letters? Background? Blah blah... Remember this is just one panel, so I guess it will be smaller at the end. And somehow I wasn't able to let Maika smug as much as I wanted. Ah I suck...
So please, tell me what's good or bad about it, so I can make the result better. I won't eat you for your critique
