I read the first chapter, curious if your writing was as good as your drawing.
You'll have to bear with me, as I have little to no knowledge of Doctor Who. I only know he has a curious manner of talking. With that said, you seem to be very good at character portrayal. I could see the characters really saying the things you have them saying, and it all feels loony in general. With that said, there's no build up, no rhyme, no reason behind the story. It's like I'm reading chapter 2, wondering what happened beforehand to lead up to all of this. The flow of the story is also very fast-paced, with little to no time to develop the current scene before we're off to who knows where.
Whether the things I mentioned are good or bad or what you intended I'll leave to you, these are just my initial impressions.
