How to create mirror image like this in corel
You mean the reflection in water ? Right ?
You need to play around with transperancy, effects like ripple etc. in DRAW. You might have to take the image to PhotoPaint for certain effects. This would be a combination of various effects depending upon the image you are working.
My first idea would be to duplicate the original motive, mirror it vertically, perhaps stretch it a bit vertically, blur it, apply a Wind filter and then smear the pixels by hand with the Smear tool.
