Some notes:
As you can see from the progression, it was always meant to be a birthday image with cake, though we definitely forgot about some form-fitting boxers at the end, intentionally or not ;3
It was a lot of fun pursuing digital painting again. I don't do enough of it. The hardest part of the approach is the difficulty of preserving the nude and then applying the clothes. I think I found a set of clothes that fits the character best (aside from the 'ripping'), but it's always fun to reach a stage where we can try dress-up. I wish I had time to make a "post-TF" image with better fitting stretch wear.
The fridge has a lot of Pokémon "Americanized" references, as well as subtle references to previous Mewtwo birthday pics hidden around. The goal was to use the drab blandness of a refrigerator and gray workout clothes to emphasize and focus the freaky mewtant at the center of it all, though I admit adding purple underwear pointing down was a little on the nose. The focal point was definitely not the eyes for this one ;3
