Err... I guess the wakes I did in that last update aren't showing well enough?
Hopefully you just hadn't seen that yet.
Sometimes it's hard to get the right mix of visibility at lower res and just overdoing it.
You're right - lots of labels, and I'm not looking forward to that.
I want to do road labels too but that might get a little small/tight.
I'll try to answer that about the lines though I'm not sure specifically what lines you're referring to.
Most of the time I am using a basic round brush at 90% hardness. It is mostly 100% opacity and between 50-70% flow.
I have pressure sensitivity and have shape dynamics on with size jitter set to pen pressure and usually angle jitter set to direction, though with a basic brush angle jitter doesn't make that much difference. I use a lighter than black tone for my lines. I can give you the info for that if you want it. I'd have to check in PS.
I also use another basic brush for soft stuff. That's set to 40% opacity and 30% flow.
I think other setting might be the same except hardness is way down, maybe 10-20 %.
And I use a smudge brush. Nothing special there. And that's really it for most all my work.
I have made some texture brushes I that I have used some but not as often.
I'm really trying to get to where I can everything with those 3 brushes. It works most of the time.
If all of that was not what you were asking about, just let me know more specifically what you're after and I'll try to answer back.
edit - I thought I should add - I do a lot with layer properties [multiply, soft light, etc] and layer opacity.
Sometimes I do that rather than change the brushes around.
Thought of one other thing to add regarding top down vs iso - I like top down if I'm trying to convey a lot of location info/labels and iso/perspective to get a better feel for the town and its architecture. I found iso to sort of block a lot of things that I wanted to show.
