just downloaded it
the layout seems good for a potential Melee map, Creeps are fine as I saw,
and Items drops also seem balanced.
What you can improve is
I see you've made more use of the Ashenvale Doodads but some of them do not give the impact the Lodearon ones do such as the rock, also considering that you might wanna use the sunken ruins mushrooms instead of the Ashenvale ones as they give a better look on this tileset
You've haven't put any doodads in the way/path there is much empty space
some Doodads are not properly placed, if you observe the south Western Gnool camp ,look at the big rock above it, the shrubs come out of it I don't think that gives a good impression.
Then we can move on to the East and West Central Creeps spot ( spider )
I see you've removed Boundaries but the end isn't giving a look as it's totally straight, maybe make it totally plain or make it somewhat curved.
more Trees are needed at start points, if you do play Melee there is something called IMBA BM, more trees will be needed to be able to wall of the base.
and lastly you might want to raise and lower the ground a bit in the path way as it looks very plain.
EDIT : drop item bug found the Golems of the spots may drop different items as one is set to lvl 3 and other lvl 4
so my rating is 2/5 until update
