Star Wars ,,work in progress"

Just a poster that I've been working at for the last couple of days. It's not yet finished I still have to get into detail with it, and by detail I mean make the sun's behind them actually round, get their faces to look sharp and accurate, work on the ship... You guys get the point. Now for the dimensions and materials: 30/23 inch (75/60 cm) gessoed board, Liquitex acrylics and Prismacolor colored pencils.
