City Scape sketch

Its not uncommon for to me to usually have another piece/sketch going along side a primary piece, this often stops me getting bored or frustrated if I have one or two other pieces to alternate too. While the subject is different to the Imperial Cruiser I'm working on, the work progress is very much the same. But with this quicker pieces I am often just doodling. But it also allows me try out new techniques and brushes.
