Here's an thought extending Digi's idea of learning form each other... how about when voting has closed, if appropriate particularly with a theme like this, the author of the image post a short 'Behind the Scenes' of how the images was created?
So for my image Behind the Scenes...
- Shot the base image of the abstract picture with three bottle of ink.
- Created an explosion layer using this snow technique but keeping the 'snow' vertical
- Masked off a rectangular selection the width I wanted for the top of the explosion down to the top of the bottle & deleted the rest
- Transformed the selection inwards at the bottom using the warp transformation to give the desired share
- Added a colour photo filter clipped to the explosion layer so it only coloured the explosion
- Repeat for bottles 2 & 3
