Hey Juandacun,
I am sorry to tell you, but I am going to reject your map.
I know Overwatch, but this does not really seem like a Mei theme at all. It just looks like a castle of snow + a pixelart. Try to use more elements, which clearly show your theme. It does not look to appealing and the jumps are repetitive in most parts.
Thank you for submitting this map and I hope to see more in the future!
