Put the grass layer above the dry mud layer. Make a new layer above the grass layer and fill it with Clouds at maximum roughness. Copy then delete the Clouds layer. Apply the Paste Alpha plugin, set to - Shades of gray on clipboard.

To use the Shift key maintaining the adjusted aspect ratio press: Ctrl+Alt+Shift C Ctrl+Alt+Shift V Then resize with Shift key.

@CyberFlame This may or might not be helpful for what you want to outline. Make a rectangular selection around the object that you want to outline. Copy, then paste into a new image. Ctrl Alt V Center the object in the canvas with the Align Object plugin. Duplicate the layer, change the lower layer object to the color that you want for the outline. Apply - Layers > Rotate / Zoom Merge layers. Copy and paste into a new layer in the original image. Reposition as needed.

Not sure exactly what you want to do. Is it something like this, which is a white block on a layer below the text that has been Gaussian blurred, then had the Opacity reduced in Layer Properties. If not then maybe you could explain further what you want.

Duplicate the background layer. With the selection active press Delete on the keyboard. This will erase the selected pixels on the top layer. Put the smiley or whatever on a layer between top and background layer. Adjust opacity.

Clone Stamp works well on the image that you posted.

This is the single layer image that you posted with Effects > Noise > Median applied with settings: Radius 8 Percentile 50

Three applications of Grid Warp.

SpacedTextPlugin.pdb file also needs to be in the Effects folder.

Your screenshot shows Layer 2 as hidden. Tick the check box on Layer 2.

Try this one.

@aijaz What you want is not possible. You can use the keyboard shortcut K and have Color Picker set to Switch to previous tool. I agree. If so, I'd like to know that reason.

Can you post your starting image here?
