While bluntly worded, the criticisms listed here are all equally valid. Let's see if I can reword them by looking at the MOC itself.
The side-view that the main pictures are taken in lets us see how gappy the MOC's torso is, especially on the back. All of the armour plating seems to signify a hard exoskeleton with fleshy tendrils extending from it in a symmetrical fashion with the two largest ones armed with blades. However them basic CCBS limbs only accomplish looking floppy and unstable to pose. If this MOC was much heavier I doubt they could support it.
The angler's lure dangling off the front is a little too heavy to actually work properly, and so sags far more than it should. Also the point of origin appears to be the neck, which might factor in. There's also no definable eyes for the creature, which iwsn't a bad thing, but the ball joints in the mouth imply they're supposed to be the eyes?
A lot of really interesting concepts, but thrown altogether with no direction in the flow of the MOC (especially in the silhouette) makes it hard to determine what this MOC's actualyl attempting to do. It's been rightly called messy and unintelligible because aside from having a mouth, lure, and tentacles, nobody can tell what the picture in your mind's eye is supposed to be.
If that's the case, why are there standards for good and bad MOCs? How come TolerantAxe is rightly viewed as far better of a builder than me solely based on the fact that I build trash the scale and quality of his MOCs?
It's because somewhere along the line, a standard was set for what constitutes as a good MOC, and while that varies from builder to builder and critic to critic it still remains generally consistent. So when your MOC consists mainly of limb pieces snapped together people are less inclined to try and perceive it the way you have because basic model means basic interpretation.
Really, I don't want to shoot you down excessively for this MOC because it's all practice. Every good builder started small, and the ones who quit moving forward either lost their passion or were shot down by someone else. There are also a lot of people who really never moved anywhere over their career because nobody gave them advice on how to move forward. So don't be afraid to make more stuff like this in the future. Be creative, try new ideas, learn from other builders, and most of all, don't be afraid to get criticism. More often than not a less than soft-spoken critic of your work has good intentions behind what they say and their ridiculing speech is mixed with tips on how to improve your MOCing capabilities even further.
So keep building. The future only stops when you tell it to.
