Artistically created patterned backgrounds with a retro-grunge feel.
The colors are a bit dirty, the textures are a bit rough, but the over all character is fresh and clean, like a pencil sketch.
1 x PSD has 8 image layers and one gradient layer, so you can change the colors, definition and opacity.
There are also 8 ready-to-use jpegs with gradient effect, as shown in the preview.
