Here’s my latest scene, everything done in Blender apart from some post processing in After Effects.
sparks seem to many than normal, but, very realistic anyway!
Thanks! This was the reference photo I used for the sparks which actually had more sparks than mine http://www.national-blacksmith-festival.co.uk/wp-content/uploads/2015/06/sparks-fly.jpg. I was surprised there were so many sparks, but maybe you’re right less particles could look nicer.
That’s cool, I love the wear and tear texture on the anvil. I agree though that you have too many sparks.
I like it! I have a blacksmith friend, and I believe he’ll love this image. Sending it to him now. 
you could make a motion blur to that hammer.
but nice scene anyways
