Welcome to the Guild tonydowler! There are some really cool items on your flickr site. Post up some stuff here, and feel free to post your works in progress for comments and criticisms. I really like your ISO city/town views, they are really kind of nice. I am sure many people would love it if you were to make some ISO style city/castle/tower icons and make them available for personal use (at least I would!) Also, be sure to check out the tutorial section as I am sure there are many things that might give you some new inspiration for different styles.
