Hey, Happy Valentine Day everybody. I was going to upload this process and just realized that it's quite a right timing for romantic picture...
One more process.
Some people ask if I use sketchup or anything for the interior, but no, this one was made with just traditional perspective tool: a ruler. Here I used an approach where I do tonal sketch and color sketch first, then render color and put over a tonal layer with multiply mode. Then an overlay mode with some mood colors and one layer for light and effects.
All the layers are below:
1. line sketch 2. tonal sketch 3. color sketch 4. color rendering 5. shadow 6. overlay 7-8. sfx
