What is so gratifying about this technique is that the strokes you made in the gesso create a lovely free rhythm running through the surface even when the illustration itself is quite tight. The texture can be brought out by deepening the recessed grooves with a tone then rubbing the the paint off the ridges before it dries, then further emphasised with drybrush highlights catching the ridges. Where content detail needs to be clear, working with a fairly liquid viscosity can eliminate interference from the texture.
