does it make a geat artist to make a great game on rpg maker 2000?

[Mizu10]

i need some pointers of making great dungeons,towns and overworlds and a good storyline for the game. because all i'm ever good at is making a good name for the game and creating the game. and all i need help with is that the dungeons i make are mostly in a snake pattern and there blank. (but you can help me with my storyline too if you like)

for the people who would like to edit or add on to the story, here it is: Once upon a time, there was a boy who liked to practice his weapon skills and then one day he met Latras. Latras was probably the the best partner you'll ever have (for stealth missions anyway). Then one day in class, there were 2 new students named Kotake and Koume. Kotake was the older and more mature witch and Koume was the younger and the more winier witch. And then they met Patrick, the weird but serious type of person and he had a heart as gold as his face. And then one day Patrick called them over to deliver a package and that's when the adventure began.......

you can probably help me with the names of Kotake and Koume's names, and i copied and pasted the sample game to edit the intro and how do i put a attached file on to a message so i can show it? And please rate my story from 1 to 10. and please i'm 13 and thats all i can think of for a story and i just started learning switches and variables.
