First of all, amazing work! Really makes me love Tamiyo, and I don't find her overly sexualized even though she's scantily clad. Probably because she's not human!
I also want to check in with you before actually attempting to use this as the inspiration for altering a card. I wanted to try a nouveau version of this using the pose. It's really beautiful and impressive regardless.
Huge fan of this Planeswalker and I'm glad to see someone take her likeness and bring out the more ethereal quality of her persona. I'm currently trying to win your alter on EBay so I can have a tangible copy of this piece. I look forward to seeing more of your work.
