I'm afraid I can't enter this as much as I want to because I have too many things art wise on my hands right now but I can offer my idea of what I though when I read your deion.
A large tree branching out, and there are actually four ravens, or wolves (Ravens would make more sense if you wanted to get technical, because they'd be 'flying' about in the trees, but I'd personally choose the wolves). Each one has an season. Bright leaves swirling about for summer, behyind one raven (or wolf), then bright flowers for spring, earth toned leaves for autumn, and snowflakes for winter. In the corners of the trees that these ravens ( or wolves) are on, the tree reflects the seasons. Summer would be green, spring is full ofblooms, autumn is brown, and winter is just the branches. the tree is dead in that area.
This is seasons, mind you. Not elements. But, the same could be applied for elements in my opinion. Just takes a creative mind <3 Perhaps for the fire, the tree could be ablaze, wind, the tree could be surrounded by cherry blossoms blowing in the assumed wind, or just branches to signify the windy and cold days of winter ( elements can revolve around seasons) for water the tree branches might instead be made of coral or just made from water. And earth would be a healthy green tree or something.
Just throwing my ideas out there, because I myself cannot partake in this contest.
