Do any of you guys and girls here on this forum, who use Krita, know how to create a good laser blast effect like this? Please let me know as soon as you're able to. Thanks!

My personal approach would be to use the air brush preset to do the main blast one stroke makes the semi-blur yellow circle, second the white center (color denotes heat in this case) and make any brush tip like the ink brush/pen scatter to make those little dots around, (only takes a few strokes) obviously you can expend as long as you wish to make the effect nice and neat, hope it provides you a least with a quick start you can build upon
