I can't say anything about your pictures, because I am on a not to great monitor now, but from here it looks like there is quite a lot of noise
There is also a lot of JPEG compression - so the quality looks poor because of that.
The D80 could do ISO100 as well and gave good results.
I wonder how much cropping was done to these images? Apart from that, the light is not ideal - which amplifies quality issues. Isn't the D90's low-light performance said to be quite good? If so, use more ISO. ISO200 should be safe enough.
I remember a pro-photographer using the D90 and he was getting great results with it (so good that it was the backup camera to his usual high-end Nikon DSLR bodies).
With a VR
lens, shutter speeds below 1/800sec should be quite safe. The 70-300 isn't a huge lens, and it has VR
. On my 200-400mm with a 1.4x TC
, I can use 1/320sec at 550mm taking advantage of the VR
feature. It works well.
Apart from that, I can only suggest to take photos in better light conditions with the sun at your back, rather than in front of you. Use Aperture priority mode at F/8 and pay attention to the histogram display. Use exposure compensation to adjust as required. There is also a display that should show you blown out highlights (it will blink those areas black). If you see that blinking, decrease exposure maybe -0.3EV, even -0.7EV if needed.
