If you're having trouble steadying your hand while you're making a line, you could try out the helper program Yvan_c posted in this thread. It's pretty neat. You just download the program (it's a small download, so it's fast) and follow the instructions in the "Read Me" text file. You use the program with ArtRage (or other drawing programs) to help steady your lines as you draw them. I used it to re-ink your drawing below. Everything was done in ArtRage with help from LazyNezumi for the inking.
