I don't even have anything on this site (yet!) - I have around four or five ideas floating in my head. One of them's pretty much completely fleshed out, I have most of the scenes planned (spreadsheet on Excel and all!... I like being organized. Maybe a little too much), though I haven't really gotten around to the 'how am I going to draw this' part (it was originally planned as a novel). It might go online next summer (2017); I want to have a huge buffer before posting, and I want the whole 'what exactly is going to happen in each scene' done before drawing (worrywart here). But also because planning is my favorite part of a story: I really love world-building! Sci-fi and fantasy are my thing.
Your story looks really cool, from what I can tell of the banner, and the description
Go for it! And I say enjoy the writing process. This is your world, toy around with it as much as you like. If ya get bored of planning scenes and stuff, explore the world a little bit. What's the life of an average person? Political systems? Beliefs, religions? Magic? You might even find something to add to the storyline. If the world was already an integral part in the first place and you already had to plan that and are bored again, talk to your characters. Or something. I'm trying to give advice here, and I'm not sure if you even want it XD. Okay, you can ignore me now.
