Kuzai, I have seen this before, and I understand that you are learning on how to create maps. Well, everyone gave you some ideas and what to do, and there right. You need to make it nature-like, and non man-made. For an example, noise it around to make it realistic, like bumps and ditches. Make some Trees around there, and make em' different from eachother, such as some dead and some cracked in between an object. The viney thorns you placed are not realistic, since there just there. . . Growing there way out of the ground. You should stick up on walls with nature growing on it, and add more of a same doodad. Using all the doodads you have listed could be very un-realistic. You need to do what is right, and what looks right.
