It's a cute style.
I see how you sliced it all up, so we could exactly re-create your scene, but when actually using assets, I prefer to have the houses I use centered and cropped.
Another big 'bonus' would be if the roofs -- but just the colored part --- was a separate layer, and the color was set to grayscale. That way, I could modulate that layer while the game was running, and while still using the one original file, have multiple houses that mean different things!
Definitely a good start, and I look forward to more! Buildings of all sorts are a big need in the art department for games.
Thank you so much for taking time to review my artwork and comment accordingly. Since I am new to itch and even posting my work, it is great to hear ways in which I can improve and what makes the best product for game developers. I will take what you said into consideration as I upload more projects.
