Hi Joshua,
it's good to see that in many more recent pictures the models are folded more cleanly than before. There is still room for much improvement, of course, but I think you are on the right track.
May I ask whether you fold models more than once? I'm astonished by the number of pictures you post, especially of models that would take me many hours to fold.
I am guessing you might only fold models once and move on to the next. I cannot criticize this too much, because many of the pictures I post are first folds, too, and often it takes some time for me to get back to them. At the same time, I do refold models when I feel I haven't really done them justice in my first fold. A perfect example is the ring-tailed lemur you also folded.
My first fold:
My second fold:
Your first (?) fold:
Now I challenge you to refold the model. Take into account the experience you made with the first model. Do you need to adjust the paper type or size? Are there steps which you found difficult, but now understand better?
I find it very satisfying to refold a model and see how I have succeeded in making a nicer, cleaner fold, a fold that captures the designer's intent more. In that I show respect and recognition  of the model and the work the designer put into it. Maybe you will also find something satisfactory in refolding a model, rather than exploring the next, different model. (Of course, that too, is exciting and satisfactory, but for me on a very different level.)
I hope this does not sound patronizing, but rather encouraging. Maybe refolding and perfecting your folds is a beautiful side to origami that you have not yet discovered and will enjoy thoroughly, too.
In any case, kudos to your enthusiasm and having acquired enough skill already to fold such complex models. If you learn to master them, I see very much potential in you as a future origami artist. I see you've given designing a go already.
