It's my first ever map, so I was really just trying to see if I could do more than make random shapes with the map editor. I tried to avoid the gas issue, and left lots of alternative paths open for flanking, and also tried to leave some spots for turrets or cannons behind the mineral lines to ward off mutalisk harassment; I'm not too sure about tank or reaver drops, tbh. Sorry it didn't turn out very well, and that I couldn't upload it properly. I was going to post a similar post right away, but I didn't expect to have uploading problems.

Basically Siabbo is right. There's too much "stuff" here. You should focus on either more standard concepts, or atleast direct the map towards some sort of concept instead of just placing stuff. While just placing stuff is definitely a good way to practice with the editor and become comfortable with all the tools, it's not something I would upload as a first map.
I can't really comment much on this, but if you make another map I hopefully will be able to comment more on it. This is like, a practice map, and it looks it. Try and narrow down what you're doing in a map so it's more clear. Focus on creating more standard and viable shapes and sizes, with clear pathing and expo layouts which "flow" properly. Basically try and make a map more "standard", more like a MOTM or a promap.
Sorry, messed up the upload/PW; trying to fix.
