Do not load all 500 at once—Photoshop might lag. Instead, split them into categories: “Oils,” “Charcoals,” “Splatters,” and “Blenders.”
All 500 brushes in your free pack likely include a “Smudge Tool” preset. Use the Mixer Brush (not the standard Smudge tool) with a textured bristle brush selected. It will blend colors without losing the grain—a hallmark of Grut’s digital oil style. grutbrushes art brushes 500 free download
