Anyone Able To Teach Me How To Build Large Walls/towers? (service Finished Please Ignore This)

So basically I've recently been having a major issue while building, that being that I cannot seem to be able to build large walls and/or towers. I can manage to make them look semi-decent normally, but I am never able to find a way to decorate a massive wall. I've tried adding support pillars, I'm adding a lot of depth to it, but I can never seem to actually make it look good.

For towers I can usually make them look okay, but I can't figure out how to add good looking non slabspam decorative features to it.

So anyone who can help teach me how to do this, PM me or reply here and you can explain how to do it here or we can decide on a time to go on Builder's Refuge so you could show me how.

I will pay 5LE for this service.

Also by 'large' I mean like 30-100 blocks tall

Already taught myself, no longer need this service.

 

5LE I will DO IT!

 

Sure, could you come on Builder's Refuge in about 30 minutes?
