Starting

So where to start? Sketching, I suppose. But I’m not entirely sure what yet. My focus is composition, but the images cannot be representational. That would kind of ruin the architectural reinterpretation that is to take place later on. So what can these images be, or what can they be inspired by? I have determined that if they are not representational, they may be interpretational. Then I can study concepts that interest me, and express them two-dimensionally.
