looking for the rest of this comic

Looking for the rest of it, any idea where it is?

The Danbooru forums are for discussion of the site itself, and should not be used for things like this.

I'll tell you that it's from a doujin named "FIRE!! CRACKER 6" by the group HEAVEN'S UNIT (I did a reverse image search), but please either reverse image search yourself or comment on the image to ask for source in the future. Do not post on the forums to do so.
