I am extending my deck and plan to make it a freestanding deck (just to avoid attaching to the current one but it will be close on top).
I plan to have a row of 4 posts on the lower level (left). Each post has 4x4 on top of pier block with metal bracket (same as existing deck):

Then on the upper slope, I am planning to use 2x8 and put on top of this pier posts:

Do you think this is OK?
