I am happy to introduce my new Realistic Watercolor Brushes for Photoshop. They are brush tool presets (.tpl)- 30 realistic, continuous (not stamps!) pressure sensitive Photoshop brush tools for digital artists and designers who want to mimic look and feel of real watercolor. There are different brushes for every purpose possible - wherever you just want to add realistic strokes and stains or paint detailed illustrations for your project. Simple watercolor brushes, with wet edges, duotone brushes, blender tools, brushes for details and effects such as realistic wet stain, bubble texture, splatter. Take a look at all brush samples on the preview. All previews are pained only with these brushes.
