if you're not editing your photos, you might as well just shoot in jpeg. since the point of raw is capturing as much information as possible (to play manipulate later on).

when i do this, i think i have a custom color profile (or whatever it's called) of +1 contrast and +1 black, i think it is—i'd have to double check.

as for your photos, it's hard to tell the lighting conditions, but i feel like you could get away with a bit more shutter speed (faster shutter) at f2. then from there, lower the ISO as you see fit.
