I came across what has to be one of the coolest website I have seen in a long time. It is called Artbreeder.com and it utilizes AI to morph and merge images together. You essentially input two parent images and it will create an offspring. There are several categories on the site that you and select from, so I presume the the AI system has been tweaked for each one to get the best results. As you can see from the image above, where I have the portrait system selected, there are some sliders for various features you can select.
The results are algorithmic, so you don't have any control over the creation. This isn't drawing, but it is an easy way to get an endless amount of good imagery. I have found the portrait mode to be very useful and something you can easily kill a few hours just going down the rabbit hole on.
The only quirk I have found with the portraits at least, is that they tend to favor very "soft" female features. You also have to pay a fee to upload your own images, which is understandable, if unfortunate.
