As long as we're nitpicking, the d in front of the theta shouldn't really be italicizes, anyway. I'd class that more as an input error than an output error, though.
Actually, many mathematics authors use an italic d while the upright d convention is standard in physics and engineering.

Is that to disambiguate it from the upright d in exterior calculus?
That would be funny, as that symbol was chosen specifically to overload with the traditional little-d notation from Leibniz.
There are other nitpicks: The pi looks too italic to me, though I can't really say its wrong (whatever "wrong" means). The spacing between the integral sign and the integrand is too big -- but this is a common problem even in real LaTex.
Overall, it looks decent but just not as nice as the maths that TeX has been pumping out for decades now.
