Hoi 09santaboy,
Sorry to tell you that your map have been rejected.
The theme is not really original, since there is already some "Sea" themed maps (SeaTemple for example), or SpongeBob maps (SpongeBob), be careful next time ! The build is not really good, it's not really attractive and pretty messy, because there is a lot of floating blocks, try to build your map on/in a main build. The parkour is also not reallly good, it's pretty repetitive and too easy for a hard, but too long for a medium, there is also too many invisible blocks on the second part, please avoid overusing them !
Thanks for submitting your map, would be really good to see more maps from you !
