Generate a semi-realistic image of a boy who embodies the essence of a 'bookworm'. This jovial character, conceptually combined with a worm's appearance, is piqued by the captivating stories unfolded in a book he reads with keen interest. He is presented in the quiet tranquility of a serene night, under the glow of a rather tiny but palpable moon. The night sky too may participate in this setting by offering a backdrop shaded in dark blue hues with a sprinkling of bright stars.
