Most creators go through creative Highs and Lows. During a High period models are tumbling out at a faster rate than can be folded or diagrammed. Inevitably after a High there follows a Low or fallow period when inspiration is lacking. There are good models in all classes, simple, intermediate and complex. One thought strikes me.
More people are likely to fold a good simple model than a good intermediate or good complex model.
Popularity is only one criteria of the success of a model. Critical acclaim is another. As in all artistic activities there are no hard and fast rules, general guidelines perhaps or rules only exist for breaking. Do your own thing. Final Words Keep trying and bombard those editors with new models.
