I understand completely where you're coming from...
...and while I understand how it could be perceived as being a lesser quality/effort work, I also feel it's a little unfair to assume that just because someone did not draw a full-bodied and/or shaded piece, that somehow means that they did not put just as much heart and soul into it. Unfortunately, unless you're looking over that artist's shoulder and/or can somehow hack into their creative process, there's no way to know or measure that kind of thing...so the best you can go on is visual results.
Of course, there have been times when I've spent days working on a piece for someone, and then all I get is a stick figure in return, so I get where you're coming from.
No, seriously...someone once submitted a stick figure to a Secret Santa.
At the time, it annoyed me. Now, it makes me laugh.
Actually, now that I re-read the Secret Santa rules, in theory a stick figure could be submitted and still meet the requirements.
It really is all about perception, I suppose.
But, I have babbled long enough, nor do I wish to cause a fuss or lead this thread off-topic.
I'll just wait for another Secret Santa that is better suited for my overly capricious Muses.
