New Work - Poison Attack

Here is some new work I've done. I'm trying to start a new plan to improve my speed. My goal is to create one effect each day (unless I am busy with other things). Here is day 1. It is a poison attack that might be seen in an action game or an rpg. It has three stages as seen in the pictures. Stage one is the initial strike. Stage two is the cracking in the ground. And the last stage is burning til it fades away.
