I've recently been getting into organic modeling, and its a hard task, the comments you are getting are constructive, there telling you to look at your proportions and tweek to match reference, as I said you can have a model that fits the front and side references bit in the perspective view dosent look right, this is where you have to use your artistic abitities to get it looking right.
I thought that this was constructive crit????
End of the day it's up to you to either take the crit and use it or to carry on with what your doing.
As for me siding with Jay its because from looking at your model that you posted for Comments for improvements, Jays about the proprotions were right, and what I would have suggested you do.
