Blue building in Jakarta

I created this illustration for cover Module that this company made for their learning material. The company is LKPP (Lembaga Kebijakan Pengadaan Barang/Jasa Pemerintah) Policy Institute for Procurement of Goods/Services based in Indonesia.I made two major color for this illustration: blue and green. The style that i used was shape with no line. I've avoid to use outline as a design on this project (almost all my project).
