You managed a good lighting that makes it immediately readable. Out of curiosity, did you try draw vanishing points and two-point perspective lines in the image itself to guide you ? From my experience, in low-resolution the 1-pixel lines is already quite "fat", and will make a big mess where they are close together. This is the kind of issue that makes me think I'd like a painting program that allows mixed-resolution layers (Real low resolution for the pixel-drawing area, high resolution / vector layer for construction lines, silhouettes, tracing images etc.)
Love it! Good stuff as usual, always look forward to seeing stuff from you.
@yrizoud: lighting and colors are painted from imagination. Typo done in PS - lowres, B/W, 2d mode. Then I played a bit with perspective, deformations, basic light.
