After a day break from the vines, I feel as though I've got a lot closer to the final rendition.
I will be doing a breakdown of the techniques used for each part just in case anyone is finding vines troublesome to do (expect it in a couple days or so!)
This is the current state of the design, I still want to include flowers and leaves but very frugally; not to detract from the composition as a whole.
Whoah this is rad, never seen this kind of concept before
WOW! is a very original pose and it really feels like the power of nature! I can't wait to see the textures of the branches. Do you do it in a real time render or with a vray render?
Wow! your champion is one of the most original characters in the challenge!! 
SUPER CREATIVE!
I especially like the rib cage in the leg! 
Thank you! 
I do have Marmoset toolbag, however I've not used yet. I'm aiming to finish both the modelling + details +polypaint in the next two weeks (hopefully!), which will give me two weeks to learn the basics and get a nice finish! Ideally I would want to use substance too, but I also need to learn how to use that too.
Awesome reference by the way!
@marianoeliceche thank you so much! 
@glubglubz Thanks, the bones have been such a fun part of the design! I've got some more coming 
I'm going to be working on it for the rest of the evening so I'll post some more renders later
Here's a quick turntable!
I have no words! 
Absolutly killing combination of bones, branches, flesh and lianas!
It is incredible!
Thank you so much!! 
Lainas! That's what they're called, this is going to help so much for the details and texturing 
I've been exploring bow designs, material etc. I do know that having the bow follow the same language as the legs and arms the focus points would be lost. So I've decided it to be a traditional, simplistic wooden bow. Which lead me to think about other aspects of the design that I wanted to include, like spirits/magic!
Also I've been working on the vines arms/hands adding more structure with bones gradually getting the vines finished and ready for detailing + texturing.
Here are a few test renders! (renders done in keyshot)
Any suggestions or feedback is always welcome!
Refining the hands and arms, gradually working through each vine-y part. A little tedious but the finish is worth it! I aim to have the vines complete mid weekish, so I can focus on Gaia.
Also found some awesome sites for bone references:
