Preview sketches before full illustration? (Patreon)

Hi everyone! I was wondering something: when it comes to personal pieces/comics, would you be interested in seeing the WiP/progress sketches or uncolored lines as I work on them, before the full piece is finished? 

I always avoided doing that because I thought it would "spoil" the final result, but after seeing other artist do that I thought I would ask for your feedback!
