Typically, you want to keep your reel to 60 seconds or less. Also, your reel is split into several parts. It seems you've combined a character reel, promotional reel, and commercial reel all in one. Now that's all fine and dandy, but you typically want separate reels for each type of work. By combining it all into an amalgamated mess like this, it doesn't give employers the information about your voice and range that you need. Also, for the characters that you do include, they're not diverse at all. You're basically including the same character doing the exact same thing for the character portions of the reel. With a demo, you want to show your emotional and vocal range. However, other than that, seems alright! Good luck and keep it up!
