My room and vision board, how do I go about starting this ?

Not sure if this is the right sub , sorry if it isn't!! The first 4 pics are my room and the last couple is the vibe I'm trying to go for, how would I go about this ? What do I need/where do I find it ? And is this even possible. (Going for a Maximus using inspiration from things I like and enjoy vibe)

Thank you !
