Hi Tusko,
I'm still learning with my camera too, but one good tip I picked up I might be able to pass on: Im not familiar with your model of camera, but if you can control the aperture, try stopping it down a bit to increase the depth of field. F11 seems to be a nice setting for me for most figure shots and will bring a lot of the away-from-center detail into sharper focus.
Remember if you do this you'll need to either leave the shutter open for longer (tripod!), or increase to ISO 100/200. You might even get away with ISO400 but any higher and you'll probably start getting some ugly noise showing up.
Hope something here helps, I enjoyed looking at your pics on the previous page
Cheers, Andy
