Well, First things First..Welcome to the Guild, The Mappiest Place on the Web
Secondus, Have some rep for posting maps in your First Post
Thirdly, VERY nice start you have there!! Glad you were able to get over the shyness, because one of the best things we do here is get people from being starting mappers to becomeing Great Cartographers. And I like your progress already. I would suggest starting a WIP (Work In Progress) thread because you will get more help, comments praise and critique over there than having your maps "hidden" in the Intro threads. Don't forget that every one here, regardless of current ability and skills, started at the very beginning of the Mapping Journey. Make no mistake....it IS a journey, but it is one well worth it and best done with eyes open in wonder at all the places you end up going.
