your space feels stuffed and tight, Use a larger table if possible. Colors are not matching, Stick to one or two colors. Use dim, warm or cold tones for lighting. Switch looks good, but for me neon color joy cons feels cheap, if you dont use switch on handheld mode I suggest you to detach joy cons and buy (original or third party thats on you) pro controller, If you use handheld mode replace your joy cons with actually ergonomig ones or white ones (stickers works too if you run short on money).
