What a great entry!
So much movement in this drawing :)

I like that you combined two different photos to come up with the final image. It really has a nice "elemental" feel to it (like the dog is in control of the water!). Your process is sound too and well documented. I like that you "practiced" with some thumbnails and sketches too, it shows the evolution of the drawing nicely!

Apart from that you have used the correct materials and medium. The final drawing is very nice. Good depth/value and Movement. Great stuff!

Ps: What's the name of the Doggo on the last photo?
