This is a picture I drew out of boredom. Drawing Santa Claus (or Saint Nicholas) on the beach for fun is an obvious mark of boredom. I used several curves to draw everything, and copied/pasted the trees from my previous works. I dropped MS Paint for Adobe Photoshop (and now I dropped the latter, because of the fees). I remember getting fascinated by MS Paint as a child (though the limits are too, well, still limited today). I was looking into MS Paint on my most recent PC. It's almost useless, especially when I can do better casual drawing on either Affinity Photo (for raster graphics, and it has the basic features of MS Paint) or Affinity Designer.
Just reading Affinity's offer of free access to eligible schools, MS Paint may lose its relevance even more. I was looking into Affinity Photo and Affinity Designer, and a child could actually do some exploration, ask an adult for help, do more exploration, and start to do better. Sure, dealing with layers can be frustrating at first. However, when one knows the true power of layers, one can look beyond the initial frustration. A child can be taught to select layers and group them, to allow them to move everything at once.
Looking at MS Paint, it's really way too bare bones. I even find myself using Affinity Photo's crop tool to be far more convenient. A child could start off by using Affinity Photo and start drawing there, with just the pen or brush. They can be introduced to combining shapes or other basic stuff for children. Sure, one can make good art at MS Paint, like that Spanish grandmother. However, it's all about accessibility and tools to get things done better. Past successes should never be an excuse not to upgrade (read here).
