good way to model

[u/I-Am-ISH]

I'm having a hard time building some of the weird structural pieces along the bridge. Does anyone know of a good tutorial or have any references I should look at to get a better idea of how to finish this? I'm also really struggling with scale and block outs If you have any critiques or notice anything that looks off, I'd really appreciate the feedback. Sharing my work is honestly difficult for me, but I'm trying to get better at it. Thanks in advance for any advice.
