I like the lighting in the first one, the others are too dark for my tastes. If this is photography, I can't speak to any effects you may have added but I would definitely have her intently staring at the creation in the bowl. Conjuring plasma energy is not easy and requires a great deal of concentration.
Add the swirls from the second one and the blurred spots from the third (both look great) and I think it would look even better. I really like your pic.
I hope you don't mind me stealing your pic but this is sort of what I meant. It's probably way too intense and I know you will do a much better job.
Oh and one last thing. Just so you'll know, I look at everything you do but I don't always comment so don't feel like no one is paying attention. Look at the stats and the number of views, not the number of comments. You do some really cool stuff and I for one enjoy it all, so there.
