Nadia Flower's is, without doubt, an amazing illustrator. I discovered her a few years back whilst in my second year of university and keep coming back to her time and time again. I must admit to often being drawn to solely computerised illustration, possibly because that's the kind I do more than any other, however this makes me want to take out my pencil again.
The drawings are fluid, delicate, almost fragile...but there is something so striking about them. I think it's the way they are confident, strong in graphic style and absolutely wonderful in general.
