Playing around with these tiles and they are so very incredibly fun, vibrant and exciting. IDK if CW is still being worked on (and I hope it is, but hey man we all have day jobs), but if you ever plan on updating this set I noticed the forest set is missing some of those...um...armpit-connecting-thingies that allow for larger forests in different shapes. Here's an image to show what I mean. It doesn't look too bad, but if there's ever an update I wouldn't mind seeing a fix.
Of course, there are a few other things I'd love to see added, but mainly I'll just be happy to see more assets.
