I've been doing concept art lately but beginning with b&w and sort of forming different shapes from what i had blotted out. I decided instead of starting off with b&w i'd try to start off with blots of colour instead. The process was quite different from working with b&w because I found that colour actually gives u feelings first instead of an illusion of an image.
overall this came out which i'm quite happy with so i won't be afraid of using more colours to start off pieces from now on.
