A simple piece with a lot of feelings to it. The colours of the characters gives a good contrast to the grey from the background. It gives of a sad feeling, that they have been through a lot.
The drawings themselves aren't the best, and doesn't compare to your previous artworks, but it is always good to try new techniques, and newer styles. A little tip, try to work on your sketches before you try to paint. Sketching every day improves your skills by a big amount.
Even though it's not your best artwork, it still gives out a lot of feelings and can have a deep meaning to the ones looking at it.
