NeonKnight or someone will be along eventually to banish your 'Blue Pip of Shame' - more about that later.
Interesting maps - I couldn't view the interactive one (Firefox or my ISP was being a pain-in-the-posterior) but the other one was nicely done - simple, nice color scheme, just wish I could've zoomed-in a bit more.
As for tips, etc. depends on how you want your maps to appear. Folks here all have their own tastes and styles so give us an idea on what you're looking to do and I'm sure some one will speak-up.
You may want to create a thread for your stuff in one of the WIP forums - rather than posting them here.
