Anything can trigger the creative thought, usually it's not one but many things and experiences. Visualizing these thoughts through images help me communicate my idea clearly to myself and other people. For these purposes I get reference images and extract data like colors, ambient and action.
No one can get it right with the first shot. Trying new ideas and ways to solve the problem is the key. Even when it seems to be the golden one I force myself to do couple more for the certainty. I used this mind map to illustrate all ideas for this project. I look in to how game should sound, look and feel through the motions.
Details is what makes any game alive. That is why I think they are so important. Here you can see my sketches to show all this little ditails and connectivity map to better understand players actions.
Sketching is my favorite way to visualize and communicate the idea

The only thing is left is to make it! Trying new things, experimenting and exploring familiar territories will not stop in pursue of the idea
