After getting my feedback from Phil I've been thinking of how I can add more fashion illustration texture to my work. I looked at some of Gaultier's Illustrations as well as various other fashion designers and found that the more sketchy stuff looks very interesting.
I'm still trying a mixture of tools while creating my thumbnails to give me some variety, I think I need to speed up my work flow as these took me the best part of an hour, possibly more to do.
Creating the city birds eye plan really helped figure out where to put buildings and how I could frame the image. I'm quite fond of 103, The road/path texture looks quite appealing to me, as well as some of the littler details on the buildings. 105 is also quite interesting, tried a more sketchy approach, it's something that I will have to practice a bit more at to make it look how I want it to.
