/ic/ - Artwork/Critique

Been painting on this on and off for about 5 weeks, still far from done.

I have no friends and I don't post on any forums so I thought I'd post it here, I would really like to hear your thoughts on it. And if someone could give advice that would be great. It's going to be called "Destroyer of Worlds" and I'm trying to make it as explosive and epic as possible. Any advice on how to achieve this? Like making things look shaky, the earth beneath the head must look like it's shattered to pieces and stuff :] I was thinking using lots of blur to to emphasize depth of field and give a sense of earthquakiness. but I've never done that, ...I'm scared...
