If you want to know how to quickly create a vegetal scenery using some masked assets, watch this short tutorial !
You'll see how to put together the PNGs and recreate the depth of field in the composition.
This image was done by Johanna Capelle (my partner on the Pixelref resource library) on Photoshop using painted cutouts of the painting pack "Spring Wild Herbs Cutout" that you can find on my Artstation store. The pack contains +110 wild grasses and flowers colored cutouts, custom shapes, PNGs silhouettes and the layered PSD of this artwork!
Have a good summer day folks !
