Jaxilon, thanks for your comment, I really appreciate your thoughts.

I want to redo the rivers slightly. I'm not keen on the smooth edges and would like to roughen them up a little and add some texture to the water. I'll look at the 'Y' intersection again too, as I hadn't thought about the effect of erosion. I see what you're saying about the tree perspective vs the houses. Hmm. Hadn't considered that. Not sure if I can fix it though, so it might have to stay. I'm amused you're thinking of peas. I kept thinking of apples when I was doing them LOL!

Finally, thanks for the encouragement. I know I'll never be a great artist, but I sorta feel that so long as I'm improving by my (lowly) standards, that's all that counts. This is only the second challenge I've taken part in, but I'm really enjoying it and I like feeling part of the community. People are welcoming and encouraging, and often very willing to share their greater knowledge and experience, which means a lot to me. I'd highly encourage other newbies or those with less skills to dive in and take part too. Every project teaches you something.
