Your choice of instruments is eclectic!!! i love the instrument you chose to work with. i can actually here the friction of the bow on violin. Most daw don't do a great job of creating that authentic violin sound.
This music gives me the impression you have created music for television, commercial, and cartoons. you do a great job of mixing in familiar Halloween/popular culture melodies and progressions. Very clean and profession. You might want to consider writing for directors, theatre, tv, and larger productions. The body of work you have submitted here would kill as portfolio piece to pitch.
