@berebobesquints Hello and welcome to Cubebrush! I hope you'll be able to find the motivation you want here.
Your art is already looking pretty nice and it doesn't really look like half-assed random drawings to me. Although I can relate to your feelings, since I tend to feel somewhat like that about what I do too. When that happens to me, I try to see if I can expand some of the themes or elements of the picture I'm working on. Or if I can add more elements that support the story that is happening in the picture.
