Don't think I haven't considered giving the old Space minifigs today's more expressive heads. But part of what I want to do in this comic is feature actual sets that Lego released and give them a story; to change the heads of the Classic Spacemen just wouldn't be genuine. Besides, I love the cute, perpetual smiles they have. It adds to the humor, I think. The newer minifigs in the comic, such as the Mission to Mars astronauts, will of course feature the modern heads.
On a related note, I sat down today and wrote down the overall story that I want to tell in these comics. While the initial plan was to do mostly gag comics, a quite cohesive and epic tale poured forth from my imagination. It will actually take many, many comics to tell it, and I hope I can accomplish this. It has several disparate plotlines that converge, and all the while I want to maintain the humor. No easy task. Essentially, the main storyline follows a group of four Classic Space cadets who were friends and graduated the academy together. There's Schwartz (black uniform) and his buddy Galinos (new, blue uniform), who you've already met. The yellow astronaut who crashed his ship in the third comic is another major character, and will play a part in the alien attack storyline that will form the backbone of the comic. There's also a red astronaut who serves at the Classic Robot Base, and he's got an important role, but he won't show up for awhile. (Don't worry, I haven't forgot about the white astronauts...) Meanwhile, there's a story going on involving Blacktron. And characters from other themes will show up on a regular basis. If I can tell this whole storyline (hopefully in about 100 comics), there's more to tell after that. The good thing is that it doesn't take an immense ammount of time to complete a comic. Probably less than an hour to shoot, 1-2 hours to put together.
