Design a futuristic, full-body portrait of Aqualad from DC Comics. The character should be portrayed in a realistic style, with a suit that reflects an advanced Atlantean design, suitable for both underwater environments and surface action. The suit may incorporate sleek, armor-like elements and hydrodynamic features, using a color palette that draws from the sea, such as shades of blue, green, and silver. His stance is confident and heroic, showing his readiness to protect both land and sea. The background could merge an oceanic horizon with a futuristic skyline, symbolizing his connection to both worlds.
