Very nice emulation on the original - love how clear and crisp the details are in the reflected pattern on the glass ball. The repeating and reflected checkered pattern is almost hypnotic. Composition is visually interesting and it holds our attention. My only critique is that that some of the color tones, especially as you travel to the background, appears to be a dirty grey/with a touch of red/pink tone. I recently found out that adjusting the white balance on the camera can help avoid some odd color casts from the light sources that our eye does not see. Adjust White Balance and see if that helps. The other thing you can do in Photoshop or Paintshop is to play with the color balance bar either adjusting it's light 'temperatures' from warm orange incandesant bulb to cooler blue shades of sunlight. There is also a box you can check to remove color cast. The composition might also benefit from a brightness/Contrast adjustment to make the contrasts visually pop more.
sharpness, refraction in the marble and twist of the background are better here. don't like the pinkish cast. aspect ratio differs, prefer the original
