These are really good, you're really progressing and getting a lot better. You should make a portfolio. You should also record a speed art and put it on youtube.
these look nice what are you using to make them? they don't look smooth idk if your going for a more rugged look. but i also do illustration and i would recommend using adobe illustrator or the pen tool on photoshop. and maybe some lighting and shading i know it sounds silly but it makes it look 100x better.
I'm using AI as well, like i said, i have little experience so they're not the best. And yes i need to work on my shading. @vulva
