Probably. I asked my art teacher today about my portfolio and he saiid that I was the best student out of my grade. However, I showed him one of my pieces and he said for that it's only worth 60/100 :\ He said I needed to expand "style" and how each expansion can influence work and create artist personalitties and art "STYLES".
I find them interesting and boring in their own ways. You get a feeling of accomplishment from grasping a difficult concept and gaining a better understanding of the world almost the same way you are pleased with an artwork you made from your own hands.
