So I promised you a review and here we go, I used debode's judging in minimodell contest as base, so thanks goes to him ( i just changed the points a little) This is only the review based on Magos, I'll later add some ingame experience!
Mesh
The Mesh itself is quite simple, but the tentacles are well done, same with the eyes! the points were the tentacles stick to the body on the backside is not too brilliant but I guess it's okay.
7/10
Textures
Now this is good use of texture, even if it's might not toooo creative, too choose the forgotten one textures for a strange one eyed thing, but it's the only fitting one i guess, and makes the model really great looking! Again only the backside isn't perfect, but I guess in this case, there's nothing to do against it!
9/10
Animations
Here are a lot of pros and cons: the first attack animation looks very promising, but it can for sure only be used as a ranged attack, which isn't bad, cause it fits well to the model. But the second attack animation looks like you run out of ideas for that one: it's just not powerful enough, looks like what i would call a "pussyattack" or something

just weak, try working on that!
The death anim is not too creative, maybe a rotating animations or something would have been better, but it is okay, so i won't deal with it too much

The spell anim is awesome, your model looks angry and then the particles come out! this is wellmade! (I'll say something to the particles later on)
The spell slam anim is nothing too special, but also not bad, so I think it's just okay, it's lacking of power like your second attack anim, but it also isn't really powerful looking!
I won't deal with every single stand animation because they are all well made, making the eye look like a really funny eye, that can also be angry (stand-3, which is maybe the best animation, really lov it, but there's a little flaw, the orange of the eyeball breaks through the rest of the texture on the left side of the model) But great job here!
I'm not sure what a stand channel is, and not sure, if I have seen this before, but animation seems okay there too, always good to have some animations for triggers!
Nothing special to say about the walk anim too!
I wanted to say something about the particles, I don't like them to much, because i think they are not that fitting to a single eye! maybe something more ugly then yellow sparks would have fitted better, but that's just me!
7/10
Creativity
THIS IS CREATIVE! even if it reminds a little of the forgotten one it is very funny and useful for dungeons for example, maybe some more creativity in the animations would have given it an even higher score!
6/7
Overall
As a result, this is a very very beautiful model and i must say great job.
Improvements could be done in some of the animations and maybe the particles.
Good job guruman!
