Feedback Please! (Particles)

Hello! Here are some basic particle systems I put together in an infinity blade scene. Please let me know if you have any ideas for future particles or know of any tutorials that might help me continue learning about particle systems in UE4. I am really new to UE4 and particle systems in general so it would be nice to get some feedback on what I’ve learned so far. Thanks for taking the time to check it out!

Also, i have been trying to make a fluid emitter (explosion) in maya… If anyone knows why the resolution looks so bad, please give me some advice!
When i added Fuel, Heat, and Density… The colors are not rendering out how I was expecting. It looks more black and yellow than it does orange like a fire.
It seemed to be starting out alright!
Here is what i started with before i used the contents details

Your particle systems seem pretty basic, but they are good for just starting out. Keep up the work!
