there is a lot of nice work done there!!!
first, welcome to the lounge.

if I can give you some advices, for your professional work, add some text to specify what you did in the shot, even if it's to say "the animation of...." just to be sure that there isn't any confusion.

Also don't forget to put your best work first, which are your work done as your professional work. I find it a bit long so I think you can cut some weaker part.
carlos banea did a really good video about reel on the animation mentor website.

good success if you are looking for a new job!

Make sure you gear your reel towards the type of job you want to get. If you want to do character animation, you might consider taking off the VFX type stuff on there. You've got a lot of walks too.
