it is a personal choice like he said. I find your images a bit on the soft side. Try using these
auto iso 400 most of the time(indoor and outdoor shots/fast moving objects)
image size L 4:3
film simulation = velvia
image quality to fine (reduces jpeg compression artifact)
sharpness standard (reduces "pixelation")
noise reduction low (reduces painting effect)
you can also with color to low and using velvia under film simulation in that combination to reduce color noise .
