Are you going to be showing/printing them with those crops? At 100%, yes they are noisy, but if they only form part of the actual image then I really wouldn't be too concerned...

It does seem a little noisy for 200 iso, but exposure can also affect noise, also what were these shot on jpeg/raw and what quality?
I tried it with a gentle de-noise and then sharpened the detail and it looked better for that. Wayne
I think the massive crop may explain it - love the original!
