It's always a trade-off of some sort. Perhaps you could have reduced the ISO by one step and doubled the exposure to 1/100sec - but then you would have gotten more motion-blur.
Perhaps, if you had changed the angle so more light would have hit the lens - maybe gotten on your knees so the overhead lights shed more onto the lens, you might have faster exposure or could have reduced the ISO - but at the cost of shadow-details.
Then there is post-processing that may be able to help you with some of the noise - but again perhaps at the expense of sharpness and textures - all depending on how you do it of course.
There is also the option of converting to B&W or some duo-tone scheme which may make some of the noise appear more like grain. That doesn't reduce the noise of course, but it may make it appear less disturbing to the image.
I think the image is quite delightful - even with the noise. There is a cetain grittiness to it and still a lot of detail preserved. Nicely done.
