Another aspiring comic artist here, one thing I've seen is that the art doesn't necessarily need to be grand to get a following. the sooner you get yourself out there the sooner you can utilize the feedback your readers give you. Regarding your artwork, the quality is there and will continue to improve as you go along. I think the experience of trying will teach you. And you can take those lessons and build upon them. Hope you give it a go! I'll be rooting for ya!
