Three Years Gone By - Speed Painting

I got a notification saying it is three years ago today that I posted my speed painting exercise from class in which we had to paint grayscale mountains in 15 minutes. When looking at the images I painted I felt that I can definitely do better now, and was curious to test my improvements over the past three years. So I picked three (a bit more complicated and detailed I realised) images and set the timer at 15 minutes.

I was right last time about time just flying by and still need to get better at using different brushes for speed painting. In my defense, speed painting is something that I hardly ever do. :P
Although they are far from masterpieces I still do think that there is a slight improvement (fortunately).
