Good start!
Cool! The shape is perfect, but the particles come apart, ruining the illusion of an explosion.
Cool Samus. There will be ways to do it with less particle systems somehow, but overall youve nailed it. Well done!
Unity is pretty straightforward, huh? for every question, there are a dozen answers with this app…The biggest thing to try and grasp is that it takes some figuring out, and that means learning a lot, which realistically means taking some time …There will always be another step to do, another concept to try-from here on in its a case of separating from the screen and stopping work to eat sleep work go to sch etc, because although everything is absolutely awesome, there is always tommorrow and even though creating games is unbelieveably cool, life is all about balance…where patience comes naturally…
I keep telling myself…
So keep it comin’ man, blow us all away with your ideas…

Very nice indeed!, but there is some wrong behavior, it happens that some times the smoke particle system overlaps the fire particle system so the explosion looks wrong
But very nice what you are doing

definitley a good start ; )
the overlap will happen if you have two particle systems in the same space - i don’t know if there’s a way to avoid that without just animating the texture of a single system to change over time - but then you might not have that shape you’re looking for.
Maybe different cameras using different layers ? could be an option

The “overlap” happens alot to me. 
Well it’s still got alot of work to be done but the stem is more real.

Yeah, much better. But now that its been mentioned, I am noticing that overlap thing.
Weird. Huh?
The particle systems flickering is caused by the near overlap of their bounding boxes. It is similar to z fighting.
I show how to get rid of it in my particle tutorial: yogware.bluegillstudios.com/site/tutorials/particle.html
