Yes, It's the same feeling I get when a touhou yuri/futa artist draws Hetero, which is pretty much all of them now. As long as he keeps the hetero stuff away from his established relationships character's all is good.
Personally, I don't really get hung up about it. Granted I'm a Herero guy and as such likes that kind of stuff, but I'm going to state why anyway. Ignoring my own sexual views, I can deal with most of his pieces because his art is genuinely good. Possible boob physics debate aside, I like how he draws women in any kind of situation. Maybe it's my way of thinking, but I just really like anything he draws. Assuming he actually a he or not.
Well, my theory here is that this image took place when DSG was younger. Which is supported by the fact that her hair is much longer than it is when you usually see her, the lack of muscles, and that shes wearing a school uniform. So it wouldn't be unreasonable to think that this picture took place before she realized that she was into women.
