That looks like a great start. The good thing is you are somebody who has been about the scene a bit which means I have a ton more faith you'll stick to your task. These things, as I'm sure you know, don't happen in months but years.
The great news is that if you can make progress like this in a month, and can continue to chip away at it steadily, you'll soon be attracting contributors who can help raise the level of the art assets a bit closer towards your aspirations. These things snowball, so the important thing is to maintain working on it and release early, release often.
