Realistic Articulated Octopus

Realistic Octopus

This was my first attempt at 3d modelling, I frankensteined 2 different models together to make this version using meshmixer. Feel free to critique, give pointers. 
The model is scaled up, however I have printed as low as 70% without issue.
I used layer height painting to make the suckers a different colour in the photo. I have left settings as is, however if printing silk make sure so slow outer wall speed down.
