It's been a little while since I've updated, but I'm still taking some time every day to focus solely on tuppers. That time is often in the evenings because of classes and work (and varies in length), but practicing visualization and tactile imposition is always an interesting experience. That, and I've got a much clearer mental image of Luna and Haya to work with when I have the time to spend 6+ hours drawing.
That said, are the hand-tingles I mentioned from before actually a sign of progress? I can't help but think it's something else, but the minute sensation of texture, e.g. wrinkles on feet or hair on top of skin, has me believing otherwise. An exercise tuppers have found interesting is laying hands, arms, or other appendages on me; clearly there's no real pressure but envisioning the force usually results in a similar sensation as the hand-tingles. It's pretty relaxing sometimes, for both parties.
