I think your reel is good! Perhaps you should explore at making more varied types of effects. Like some environmental effects and shader work. Im no pro at this but maybe show some process as well, I keep getting told that recruiters like to see how you make things, so show the textures, material network and just the general process of how you achieved the result.
some of the smoke and fire stuff had some obvious “spritetyness” but I don’t think that is a hard to solve problem. Also agree with the above, try creating some more varied effects, and see how far you can push all of them.
Thank you for the advice, I’ll try to improve the fire and add more different kinds of effects. Do you guys think it’s better to put the fx breakdowns in the reel too, or in a separate place (like a blog or something)?
