have you considered stronger borders on the sides of buildings to separate them from the background
Hadn't really considered it, no. Maybe I will give it a second look, I like what you've done it the edit. Thanks for that.
I also think it's kind of weird how some places have shadows (e.g. windows and doors), while the buildings and walls do not cast any shadows.
I am planing to use these tiles in a game, eventually, god willing. I figure I will add shadows to the larger things with code instead of artwork. Save myself a lot of work that way.
In my experience, the best way is to help other people with C&C in their threads. Then they're grateful to you and check out your thread more often.
I would like to offer more help but feel as though I am qualified enough to provide guidance to only the very newest of pixelers.
What is your end goal? It is such a large piece, where are you going with it?
This piece is just being used to overhaul my preexisting infrastructure tiles (roads, sidewalks, docks, etc.) I like working in mock up format.
I think you might need to take a break from polishing what you have and start adding new assets. Start filling the streets with objects and maybe people eventually. After you have developed some more skills and filled up the environment more maybe then you might see ways of improving what you have now.
This is great advice. I've been struggling with these for too long. I'll start working on street lamps, creates and barrels.
