Yet another nebula-speedy

Painted in a free hour between lab reports, computers-assignments, and even more physics. It's amazing how time-draining some classes (especially lab) can be... had maybe 5h of free time over the past month. So yeh, sorry for the lack of art lately. Vacations start around the 17th or so, which should give me the chance to work on the 3 WIPs I still have on my computer over the Christmas season. Slap me if I don't
