I would be more than flattered if you took inspiration from me for the Instagram actually, so, it's not copy at all! I also suggest to chose a fix layout, such as Wide, Portrait or Square, I've ended up with Portrait because being mostly made for paperback version, some panels are very tall, and so the former two would be difficult to pull.
Be also sure to release the fixed version (I mean, after some correction such as grammar or graphical errors) on there, as You can't update it afterward, and if you want to keep the reading smooth, you should archive all the following parts, just to update a part... and I've did it quiiiiite a lot!
