I think you're improving, but I think if you slow down and submit say, 1 good wallpaper a month rather than 3 or 4 a week, you'll improve much more. As you can see by the number of reviews you get and downloads, people here are not very interested in your work because A. It looks rushed B. You sub too much. People are probably not bothering to even check it out because you've established yourself as a mediocre artist who subs too much. That's too bad, because you ARE getting better. Slow down and let these suckers cook. You've got great ideas, really work them over.
