Please ask about steps on pieces, and I can answer as best as I can recall.
Think about your subject.....sketch ideas, consider the mood and colors.
Draw.....sketch it out and develop your plan.
Start light (even with the drawing)... this is critical in watercolor. Save the white areas with planning, masking fluid, taping off areas, etc.
Build up with color.
Add accents and details.
Take time between steps to change your paint water, take a step back, and consider what needs to happen.
