Nice idea... you should cut out the wheel...clone stamp the boards back in...then liquify the wheel and distort to the square... everything distorted is too obvious and distracting... g/l and keep on chopping!

I love the idea author but woodztockr is correct.. if you kept the back ground normal and only squared the wheel separately, you will have a much more powerful piece.. good luck

done using the liquify tool

I agree completely with what woodztockr and Golem say. Would be way way more effective if the background is "normal" (with the round wheel removed, of course). Good luck!

Make a dup. of the first then do your liquify on the second. The add layer mask and go around the saved area with it. I will help
