Need help with Sharkfood Island

[Juxxthefluxx]

I recently played a match on Sharkfood Island, that I lost quite handily. I'm a relatively new player. I've placed in gifted, but still have relatively few games under my belt. My hope is that by sharing this replay, I can get some insight into what I could have done better, because right now I am just not seeing it.

I am more than happy to answer any questions on my thought process.

Also, I would love to know if any issues you see with my play are somehow connected to this map (because it's small perhaps) or more general stuff that I could work on.
