Peace Rose - then and now

I thought this was interesting. The first image is a shot of a Peace Rose that I took a few days after I got my D70 in March. The second shot of the same rose was taken last night. I can see some significant differences in focussing and sharpness. There are other obvious differences from the different size flower bud and the colour differences which presumably is to do with taking the shots at differnt times in the flowering season. (I think I might have saturated the colours in the the first one a bit as well).
