Frankly, I just typed "graphene structure" in Google Images and picked one which seemed suitable for editing in Photoshop. But I can probably use another image, if it's more accurate. Have one handy? :)
I apologize, I've messed up, it won't work either. Seems like it's best to use schematics with single lines. The image you have used is OK, even though this notation is missing electron delocalisation.
You can take back an upvote for my previous post :(
Science is hard. Upvote can stay for good effort :)
I spent some time browsing Google Images, looking for a better image, but couldn't find anything more suitable really.
Just leave it, it's fairly OK. And looks good.
I appreciated your comment -- it's worth at least looking for something more notationally correct. But yeah in the end I think it's fine. Scientists routinely abuse notation out of laziness [source: a lazy scientist :-) ]
