I am not very experienced with DALL-E but may I ask what kind of prompt did you use to generate this image? It looks like it serves its purpose very well.
"a pixel art image of an extremely old and overgrown
tree. nestled against the base of the tree is a full suit
of armor completely intact, presumably held together
by the remains of the ancient warrior inside. the armor
itself is as overgrown as the tree, with moss, vines,
and rust covering it. the background is the rest of the
forest and the time of day is twilight."
