I finally found the time to make an edit of the giraffe, so here are a few suggestions. I'm sure a lot of it's just a matter of personal preference, but maybe it'll give you some ideas.
First of all, I think it's off balance. Centering the neck and head more makes the pose less dynamic, but I don't think you have much of a choice with tiny legs and feet close together. It would either need bigger feet or longer legs.
I didn't think the brown you're using as an outline works very well. I'd use solid purple for the parts in shadow and the darkest color from the animal on the brighter parts. Mixing two contrasting colors like that just makes it look muddled.
I also think cleaning up the outlines would be a good idea.
I experimented with the limbs a bit and tried to keep the tiny legs while giving them some more "filling" rather than being mostly just outlines.
The arm around the dryer looks weird. It's not really holding it, just placed on top of it.
The highlights on the head are pure white without the buffer shade you're using on the stomach. There's also a shade of orange you're not using elsewhere around the mouth. I removed it and added another shade to the dryer to make it fit more with the rest.
