I don't feel just making the original effects bigger will impress me any more than what it is at the moment, what you need is better visual effects things that look more impressive, for example if i was to use fire make it look like i just channel magic from something like the sun that hits my staff making it go on fire then that energy projects at the enemy or if using "Stone" then you can see the magic rising up from around my feet through my body then into my staff making it look like stone, then it projects at the enemy and so on.
