Chainsaw carved pumpkins

I picked up a couple pieces of a tree that fell(Broke off ) a block away from my home. the wood was a pale orange so I thuoght the logs might make some nice pumpkins. I didn't get to carving them last year and the wood did develope the darker outside and greying over the winter. So I can't leave them in the natural wood color unless I find something that will stop the greying.  I incorporated the shape of the log parts into the pumpkin shapes which make them look more like some of the funny natural grown pumpkins. Put a coat of Pumpkin Orange spray paint on them but still need to paint the stems a brown or green. Maybe I'll put a face on one.
