Show HN: Improve and get automatic feedback on drawn sketches

As I was struggling to draw people that actually looked like people, I created a website that compares a hand drawn portrait of a person to a photo. Instead of rapidly looking back and forth at the end to see how I did, I ended up making some software that automatically puts the two pictures together and blends them back and forth. This way you can see small deviations in your drawing and areas to improve.

Instead of asking for feedback every time, you can see your own mistakes and learn to make the proportions, shading and edges as close to the original as possible.

The site is below with a few examples you can look at to see how it works. http://drawingapps.ca/portrait-vs-photo-comparison
