Thank you, haha! Oh yes, the plan is to keep the colour palette updated across all packs to work seamlessly - I did plan it a ton, but you know ... things evolve through time ;) 

Also the next steps for this pack in particular is to create bike lanes (already on it):

Including the building blocks, of course (since everything I create is made out of 4x4 and carefully planned, just like in the UI design, multiplied by 4 (so, 4, 8, 12, 16, 20, 24 etc.):

Apart from that, one of the next steps surely is to create props such as Traffic lights, benches, fire hydrants, signs, bus stops etc. Thought this will be right after the bike lane update.

Since this pack is inspired by EU, I would like to expand it a bit in a sense, to also have it expanded with US inspired signage (eg. double yellow lines, road signage etc.)

After that I will be experimenting with various textures for sidewalks & roads as well - worn out feel, potholes, sewage drains, sidewalk etc.

And mainly, re-organising everything to its sense and easier export to game engines such as Godot, Unity & Unreal. Althought there is plenty of tutorials online, I might create one or two specifically for my packs as well.

Stay tuned for more! ;)
Pro tip: Any suggestions etc. feel free to send them my way, I will most likely consider them!
