By far the wolf one is my favorite. Nice shading and development, the only negative thing I could say is the stucture of the images, there doesn't seem to be a focal point that the viewer's eye is drawn to.
theres not supose to be a focal point in my drawings or paintings,your supose to look at them in a no mind state.and as you do it actives that inner self of you to heal..or intune with the angels,guides teachers and so on.Kind of like mandela's,use symbols in art for healing.
