My, that's a fine shade of seagreen-and again, nice understated effect on the background. Niggling suggestion for the day: ever considered saving pieces like these in a different format (.jpg, .gif, etc.)? Some of these .PNG files are a wee bit huuuge. Feel free to ignore if that last bit isn't an option, of course.
Saving em in PNG format is a habit I picked up from one of my classes. We worked with large files all the time and to really see the detail you had to get in there. Thanks for letting me know though, sometimes I forget how big the images actually are, haha. I'll keep it in mind for future drawings.
