Bubble Walkthrough

A couple people asked me to make a walkthrough/tutorial on how I do bubbles so here it is~ owo

I use SAI to draw but I think it could work on a lot of other programs.
(these are all on different layers)
Here's how I did it:

1- Draw a circle that isn't full closed and add lights to where ever in the bubble
2- I take the airbrush tool and go around the edges of the bubble to give it a "glow" effect
3- With green, I go around the whole bubble including the part that's open. I lower the opacity and make the layer multiply, blurring some of it.
4- I take blue and purple and add little dots on top and bottom of the bubble just for color and lower the opacity to around 30-40%
5- Using the airbrush, I take the purple and do a circle in the middle of the bubble. Then blur the purple to make it fit in a bit more. I also lower the opacity if the purple is way to vivid~
