Dunno if anyone else is trying to find the source on the other manga from the previous page, but I'm still trying every once in a while.
I have done source-finding before, and I find one trick that really helps is to do a very simple check on what several people think is going on, and to just throw around keywords.
As for me, I'm seeing a lot of things I don't know how to search for. There's a big dog monster/demon thing in a space suit who has crazy eyes. There are two characters named Miyuki and Aru (maybe), but I don't know of those are the names of either of these characters.
The lack of suggestive themes also might hint at the fact that this is a serialized manga rather than a doujin. I've read a lot of manga, but this one isn't one of them, though the art looks strikingly familiar. My last resort, therefore, is to look through every single manga in this list:

I'm almost at this phase, to be honest. I just hope the real thing isn't a disappointment.
Edit: @omglawlz: I can translate Japanese, but it's time-consuming as I work alone. There isn't a lot of text there, so if I get some free time I'll give you a translated version. I've personally translated several of
his short stories, but I did it for myself just to read it once. Most of the time I don't save translation work as I just want to know the story the first time.
I prefer to read things in Japanese as their language is just so much more interesting and has a lot more flexibility in the way you express things. For example, in English, we have one way of saying "I". In Japanese, there are more than a dozen. It's really hard expressing the differences between the tones of "I" when you have one option to use.
