I drew this image myself, it's supposed to be a luna moth.
I used the pencil feature and the paint bucket feature on GIMP.
I took this photograph myself, on a farm in Kunkletown, Pennsylvania. No features necessary!
And here's that same farm, with three different filters.
With the Circular Motion Blur Filter
With the Engrave Filter
With the Cartoon Filter
Now, here are two more images. The one of me, I took myself. The one of the UFO, I got from here. No features necessary!
Oh no! I got abducted by aliens!
Just kidding. I am safe here on earth.
Anyway, that's the blended image. I know it's a bit rough around the edges, no pun intended, but I did my best, especially since GIMP is a little jenky with this feature.
I used the Blend feature, set the mode of the UFO to "luminance," and airburshed the edges with the help of the dropper tool.
