Interesting

I do find this one to be not bad and interesting. I do think your use of white space here is a bit bad, but nothing terrible. I would add more background features or textures and maybe even some designs to draw it all together. I understand with portraits that you need a focus on the main character but I feel based on your other work you could add so much more to the background here. I love the parot thing on the shoulder the most, it does have a top hat afterall, and the general teeth expression this man has as a character. I think that your cartoon art style is very unique and I hope more comes from this.

I would add some more details to the background and limit the white space being unused.

You have a really good overall structure, but there's something about his nose that stands out in a negative way.
I love the bird though. Not sure as to why, but I'm really drawn to it!

Wow !! Man This Looks Awesome!!

This is cool! I like the top hat on the chicken thing.
