Greetings! I really like the look of this game. It's an interesting blend of ideas from other town builders and god games, and I could see it getting really fun.
I have noticed that Creo uses free audio, though. Are you intending to replace this with custom-composed music and sound effects as the project progresses? If so, and if you're looking for a composer, I would be very interested in helping with that.
I don't really have anything super-close to Daniel Birch's style to show, if that's a sound you want to stick to (it certainly fits nicely!), but I could definitely adhere to an understated, relaxing, synth-pad-heavy tone like that. Or, if you wish, add in a few folksy elements to bring it towards something like Age of Empires, or orchestral, for a slightly more RPGish flavour. I would of course work with you closely to make sure the music and sound effects are exactly what you want.
Please, take a look at my website if you'd like to hear some examples of my work. Regardless of whether or not you'd like me to work with you, I wish you the best of luck and success with the game. ^^
