Perhaps it would be better if your post came across as more of a question.... something like
"How could this image be improved' and put it in the critique section. or, start thread asking people if they revisit their best sellers or if they simple try to create something new.
Remember to give the thread a good descriptive subject. You did ask a few questions in your first post but the subject of the thread is about how well your image is selling - it is a statement. If you are asking a question in your first post, the subject of the thread should reflect that question.
Also, I'm not sure if you meant to link or show your image and forgot or it didn't work - but if you ask questions about a specific image, it is good to link or show the image so we can see what is being discussed.
I'll lock this thread for now and you can restart the thread as you see fit (as per the suggestions above).
