MOC - New Life Tree House

I am a huge fan of the LEGO Tree House (21318-1) set and it's also one of two big sets that I owe, so it seemed natural to give this a go as my first big alternative design.

Some things didn't need much changing; for example, I used the same principles of the original set to create the main tree trunk. But I thought to myself: "What if the tree house was build on an old tree trunk, that then sprouted new life?" This theme carries through in my MOC in the way that a major side branch then gives way to a new, vertical trunk that reaches towards the skies.

The builders of the tree house supported this new growth by adding supporting anchors to the branches in a number of ways, helping the vulnerable branches to grow thick and strong.

I hope you enjoy this MOC and constructive feedback is very welcome!

Notes and acknowledgements:

• I've tried very hard to make sure that the main structure is as structurally stable as can be, but due to the very nature that you have a very large set of branches on the one end of the build, means that the central structure will be vulnerable - please take care to always support the main structure whenever you place a part.
• I couldn't figure out how to represent the string cord (56823c50) in the instructions, but I tried to explain how to connect it. Some photos attempt to show it. (Perhaps in my next MOC, I'll get it right!)
• The MOC makes use of both autumn, summer and the extra parts of 21318-1.
• The original set had a good approach to building the main trunk, so I started out by following the same steps - but then deviated along the way. Credit for those original steps do, of course, belong to the designer of the 21318-1 set, Kevin Feeser.

UPDATED INSTRUCTIONS: After a recent scan by Rebrickable, it became clear that I had counted the 98138 in Reddish Brown a few too many times (I used 11, but there's only 8 available in the set), so I had to make small changes to the set to remove 3 of them. The count will now correctly align with what you actually have available to you. I also used the opportunity to export high resolution instructions, which will hopefully be welcome :) Apologies for any inconvenience!
