Since then, Nathan has developed a career as a contemporary artist, whilst helping to inspire young people by teaching art in schools, as well carrying out charity work.
Ers hynny, mae Nathan wedi datblygu gyrfa fel artist cyfoes, gan helpu i ysbrydoli pobl ifanc drwy addysgu celf mewn ysgolion, yn ogystal â gwneud gwaith elusennol.
