I tried what you did (475 resample to 225 pixels) in PSCS3 and my results were very good….

Took an original photo and cropped out 475 x 475 pixels at 100% crop (no change to pixels) (image 1).
Then I re-sampled the 475 to 225 using BiCubic Sharper (2), and also BiCubic Smoother (3).
I put these together in the same image file without altering any pixels so you can see them together. Just view it at 100% zoom for a valid comparison. (Other zoom levels will result in further re-sampling by the computer for viewing purposes, you don’t want this!!)

See this link for the image file.

As you can see, 2 is actually sharper than 1. Image 3 looks very good also.

I then printed this image file at 50 ppi (14” x 9.5”), 100 ppi (7” x 4.75”) and 300 ppi (2.3 x 1.58”). All three looked the same in each printing ppi. Yes the 100 and 300 ppi looked better than the 50 ppi but this is what is expected.

Maybe you did something to your image when you cropped out the 475 pixel crop. But again, these look great.
