Working on a Bison Totem

So here they are....all for colors of the Medicine Wheel, four directions.  I had a sketch idea..

not sure where it's going at this point...the bison are separate now and will come together in a row down...

The style of this series will be like Greater-She Bear and the Snow Owl. 

But after a point with my sketches and designs....I don't hit a block it's now open for inspiration to come in and direct the show so to say...
