This fella looks pretty rad. I especially dig the fragmented floating crown he's got. Not too wild about the shading, though. It's not atrocious or anything. I just think you could have gone with some better color choices for it. Then again, I'd take anything I'm saying with a grain of salt, especially if you've seen anything I've done recently. I'm still trying to figure out what ancient god I need to offer sacrifice to so that I may obtain good color choices. Maybe I should just swallow my pride and look for a pre-selected color palette. But I'm not sure how well that would teach me to do it on my own. Anyways, you're pretty talented. I'm sure in time you'll undoubtedly improve.
As for that whole, making a world comment. If you ever do decide to make your own world, I'd love to see or hear about it. I always love hearing about the world's people make in their minds. Making a world is one of the more interesting things someone can do with their imagination. I myself have made a few worlds in my time. Wasn't until a few years back I made one that I finally liked. One day, when I'm good enough, I'll bring it to life.
As for you not uploading for a while, I'll tell you the same thing I would tell anyone else. Don't stress yourself out too much. Sometimes other things in life just take priority. But I also understand that it's a constant struggle to stay relevant. You got to find your own pace and then improve it from there. I'm sure you'll figure it out.
