Nice stuff, I like what I see.
Here is my two cents.
- It’s all staff spells. While certainly cool more diversity in effects would be nice to see.
- The icicle spell (5 seconds) the staff swings just a moment too late it would be great to pull it in just a moment.
- The lightning (38 seconds) feels a bit too liquidy for lightning, this really comes down to personal taste though.
- The lightning orb pop (41 seconds) feels like it does not have enough energy, and should rather pop/explode with more force.
- The spherical fire effect (48 seconds) looks great, however perhaps you should feather the edges out (Effectively discussed here) This really is just to soften the effect and hide the tell tale signs of using a mesh sphere.
Overall I do like your effects, I would encourage you to make use of the principles of animation within your effects.
Mainly
-Anticipation
-Follow Through
-Timing
Hope it helps
