Considering this was a 2 minute drawing made on my computer that wasn't originally for newgrounds and was not made to be representative of my drawing capacity I think you should look a little bit at some of my other stuff before telling me what to work on.

Also, not that I don't appreciate the constructive criticism, but I don't really understand it. Why make steadier lines with a creature like this, who is mostly curves? Do you mean make thicker lines or thinner lines? And I have no idea what you mean by weight.
