Music practice - in progress, part 2

Here's the progress so far on Music Practice.  I added some more musicians, cleaned up all the lines, fixed the face on the first musician so it doesn't look so doofy, and did a first pass on coloring it.  All in all, not bad.  I certainly use more attention on the background and setting, but this would be an acceptable frame for a comic, I think.

Is this a sustainable style?  Hell, no!  This took longer than I'd like to spend on a single frame, and it's probably too hopeful to think I'll get good enough soon enough for this style to be sustainable.

I recently started a comic workshop at work taught by Rad Sechrist, one of the talented story artists.  (See "Explorer: The Mystery Boxes" for his comic story "The Butter Thief".)  We had the first class last week and he had some really good practical guidance to give, including, don't sweat all the details because most people are paying more attention to the story than the art, and it's more important to finish something than to get it perfect on the first try.  Hoping this workshop will give me the kickstart I need.  I'm starting to apply some of his brainstorm techniques to further the plotting process.
