Honestly, I have to say that it is much better. However, some irks:
you used way too much of the same type of tile, like, really way too much. The weed? yeah. cut down on the amount you have, and use different types. Lots of different types( i.e., use all of them.). However, make sure the ones that you use are passable; if you use too much of the weeds/rocks/whatevers that are not passable, that would just become annoying.
The tree thingey has really improved. Regi's advice for your style of mapping should be noted: use different layers, namely two and three, to ad an extra level of trees. Not covering over your current level, mind you, but to add that extra... oomph.
Okay, with that out of the ay, check this out:
what type of maze thingey are you doing? Is this dungeon of yours one giant map, or a series of small maps? If it's one giant map, make sure that the paths allowed for the player to view are a bit narrower than what you have now; right now, your map is pretty much one giant screen, rather something with an actual maze/path for the player to follow.
As before, check out everyone else's maps, and just try to copy them until you're capable enough to make your own style. With proper skills, RTP looks epic.
