The first time I created a Tumblr header. After a bit of google exploring together with my love, we found out what the perfect ratio for a Tumblr blog header is. Separate the white with a mask in Photoshop, and export it for web as a PNG. Easy as that.
The drawing was made with Uni Posca and Molotow markers. Just a quick sunday project!
