Patrick -- its understandable that after working on a similar bunch of works over a year and a half, you're a bit burnt out with the idea. i would suggest changing your working method slightly rather than abandoning everything you've done so far.

your work seems to be well-planned and then executed according to the idea you've developed. maybe it would help to open up that way of working. how important is drawing in your work? its a quicker medium so maybe you can explore something more spontaneous as you are responding to news events and daily tragedies.

take a closer look at the sources you're using. i would suggest looking closer at the news sources - the imagery and format -- in addition to your research in medieval art. the artists you mentioned basquiat and haring made paintings that were visual responses to pop imagery they were seeing around them. consider how the visual style you're using can make a statement that is equally contemporary.

take a look at the paintings of John Wesley and Carol Dunham.
