I follow quite a few blogs, mostly via the excellent Feedly which I moved to after the sad demise of Google Reader. Very few, however, I subscribe to receive via email on a daily basis.
A fresh drawing everyday by Hugo Costa is one exception.
As his blog title suggests, he posts a new sketch every day. Some are black and white, some are colour, all are beautiful.
While I have been unsubscribing to a lot of email newsletters over the last few months, this is one that I look forward to daily. I find his art inspiring. The image above, which he described as being from fish-eye perspective, is one of my favourites.
