Honestly it looks like one of those cartoons - you know when the rambunctious rabbit jumps on something, and it squashes down and springs back up as if it were a rubber slinky?
It's very - very - very round. Barrels are more cylinder shaped then they are circular, although it appears as if your missing the bottom of it at the same time - like it was cut in half.
Either make it much thinner, make it so it's laying on it's side not standing up, or double it's height and you've got a fix.
I'd suggest giving it more height, with a minor slimming down at the mid. Good work otherwise.
BTW you can edit your prefix in the title by reporting the post and asking the mods to change it to _______ (blank being whatever you'd prefer). They changed my prefix on a thread from, they'll easily be able to change yours as well.
I would suggest changing it to "map/autotile" since it appears to be an addon, as opposed to 'other'.
