Hei , i'm happy you like my drawing .
I made the same mistake as you with Dragon Age but after Alistair dumped me I wanted revenge so I made him have a demon baby with Morrigan so I can survive and then ran away with Zevran. It was totally worth it.
Yes , this is the control ending. :3 Part of the magic of this drawing is figuring out what it means , depending on how you played and if you romanced Thane or not, your own version of it is really interesting. For me it was a way I imagined Shep coping with the end and her choices through the game , Thane appearing there is something she imagined to ease her pass.
:3 Feel free to post it on FB, no I don't have my own FB, sorry. Hei all I ask is leave a link with my dev account to it and of course share with me the FB album link, I wanna see all the cool art you gathered!
