Hey!
I love the theme of this map, really brings back some nostalgia from paintings which is neato! One thing I will say is the jumps seem somewhat repetitive, with this try using different types of blocks within your jumps (flower pots. piston heads, water, cobble walls, ice and player heads) to allow for a more enjoyable experience! Other than that, the map fits both the difficulty and length of an easy map so good work on that!
I hope that you can take my review into account <3 PS, I am not a map judge I'm just giving my opinion.
I wish you all the best with this and future submissions!
