GhostSpace is a model designed to convey a dark and muted style that feels like a memory. This model is experimental with heavy stylistic bias - it is not a general purpose model. Despite this, the model is quite easy to prompt (prompt examples attached on the model images).

Note: The example image seeds will not yield identical results in the automatic1111 webui. I use a custom noise generator that has incompatible seeds.

Recommendations:

Configuration scale can affect the sharpness of the image. You can get very interesting images at a wide range of config scales. A scale of 13 can yield sharp edges and bold contrast, whereas a config scale of 5 might lean closer to a watercolor look.
(highly recommended) Upscaling is a very important for getting a clean look. If you don't, then the model can tend to generate a heavily compressed "jpeg" look, which is generally undesirable. I personally switch between R-ESRGAN 4x+ Anime6B and ESRGAN 4x at a denoising strength of 0.5, but any upscaler works fine.
This model is designed for artistic exploration, so I'd recommend being experimental with your prompting style. Example prompts are provided attached to the example images.
If you want to avoid the watercolor look, adding "watercolor winter cloudy" to the negative prompt can help with that
