I just happen to have emerged this photo taken with my Thinkpad tablet at work. The drawing itself is no more and all is left is just a tutorial “On how to draw a sexy Rainbow Dash” as someone online insisted.  
This is just the most minimalist tools I could have around at this moment, a terrible pencil and some paper. And the lighting, took in a office an evening of november 2017…
 
Sorry for the pic quality that’s all I got from this thing but I might vectorize her at some point, that should be better… but I prefer to know this is here rather inside some mobile device that uses a SD card as main storage.
