Help with Model

Ive been working with models and building my portfolio over the past few months. I do a lot of TFP work with models from a facebook group. One model I worked with when I first started on a TFP shoot, the photos were garbage. Lighting was awful. (my fault) Poses were trash (my fault) but I also had a few problems with the model. Upon realizing the photos were trash, I paid her for her time, gave her some photos and wanted to put the whole thing behind me. Apparently I paid her much more than she usually gets. Ive since become a much, much better photographer. Now this model repeatedly keeps asking me when we will have another photoshoot. How do I politely decline without harming my reputation or coming off as rude. What would you do? via /r/photography https://ift.tt/35kH8m4
