Hawkflight pretty well sums up my thoughts on this particular situation.
You're forgetting the most important part of constructive criticism. "This is wrong, this is why, and this is how you go about fixing it." Without that last part, critiques lose their value.
Basically, spending more time saying "this is wrong" than you spend saying "here's how I think you can fix it" isn't constructive because you're critiquing someone else's creative work.
This MoC isn't bad. The criticisms stemming from the CCBS and Technic overlap are valid, but mostly because having Technic on the Torso and then CCBS arms makes the differences between the two glaringly obvious. There are plenty of examples on the boards of MoC's that nicely blend the two, so it's definitely worth taking a look at some of them to see how they get around that issue. (Standalone Ball Joints are your friend)
I can see where you went for the Feminine figure, but I think the biggest thing working against it is the Inika Shoulder piece on the torso. It tapers down when it should taper out - the hips (especially on a character such as this) aren't the narrowest part of the body.
I'd work on fleshing out the front of the torso - specifically smoothing it out. The back actually looks great, but I think the texturing on the front of the torso is definitely contributing to confusion and looks odd.
As for those people saying "This shouldn't have taken 4 years" don't listen to em. Not all of us have the time, patience, or skills to actually make MoC's. What's important is that you made it at all! I haven't built a non-Inika mod moc since before Bionicle G1 ended. Hekk, I haven't build a moc since before Bionicle G1 ended. Ain't got time for that
