Don't be afraid to start posting some of your own work as soon as possible. There are a lot of great cartographers here willing to offer friendly advice and suggestions. If you're new to digital cartography, be sure to check out the Software forum for some ideas of what you might want to look for in that realm. Also, there are some great tutorials as well, and one of our members (Vandy) has been working to re-create them in PDF format for ease of download. Those can be found in the Tutorials section.
Look forward to seeing some of your efforts soon.
