I need an external opinion

Actually your map looks pretty good. Though I agree that I can hand-draw a map faster than doing it digitally - at least at the level of detail I try to achieve in a map, what software brings to the table let's me include in the map that which I cannot achieve by hand - 3D depth in elevations, shadows, beveled shapes, readable text. Even my hand-drawn maps are not hand-drawings alone. I always add fractal color mixes, shape beveling, edge feathering, varying uses of transparency. Even if a maps of mine is primarily hand-drawn, I don't draw all elements on the same piece of paper. I often draw elements of my map as stand-alone drawings that are scanned and made into a map object. Once all the elements (trees, furniture, etc.) are created, only then do I draw in the walls of a structure and the terrain. Once that part is fully rendered with included effects, I populate the map with the various pre-created map objects. So I never draw everything on one sheet of paper - it might look like I did once its completed, but the same steps I do for a purely digital map are the same with my hand-created work.

As far as getting professional results (you're on the right track) from working with the Cartographers' Guild, its going to take a few months of following tutorials, experimenting with different maps to get to a level that you can bring you satisfaction. It will be relatively short time, but still require effort and time on your part to achieve that. There is no instant, fast and beautiful results from joining the guild, it will still require work on your part.
