Not bad at all, are you getting a game engine and considering properly learning code? If you do that you could probably put all of your ideas into practice. It takes quite a lot of work but for me at least there's nothing else I'd rather do, I love being able to draw anything and bring it to life in a game.

You could also consider taking your art to the next level and get really good at doing full on isometric art like the Baldurs Gate games or Pillars of Eternity etc. and design entire maps.
