WIP - life &soul

So last night I sat up way too late drawing this idea that I had a few weeks ago about having each of the elements - earth,air,fire and water onto a tile and putting them together with the soul in the middle of it all. Finding tangles suitable for air was really tricky, it's ended up more like weather than air. ( any suggestions welcome). 

So this isn't shaded or anything, I'm going to make a few copies of it like this add some colour onto one or two and shade another see what works best before I mess up the orginal one.
