Really like the style of Godus too, the lighting in the lower right of the example image is really nice. Subscribed and looking forward to seeing how this develops :)
I would really recommend forgetting clothing right now and focusing on the overall anatomy, there are some issues with the arms and hands for example. Keep it up!
Depends on the game. If you have a regular grid, attached can be better. Infinite runner for example. But if more organic results are needed, then modular is better.
