Stong potential, glaring weaknesses.
I think you have a nice voice for soft toned reads, but deliveries like "reconize", "that matter the mos", "american airline dah com" (should also be "airlines", with an "s"), "b'as it might someday become", "on the moun-EN", "architec", show me that you really need to work on tightening up your enunciation, along with better training your ears so you're aware of such occurrences the moment they happen. It's so frequent that I'm beginning to wonder if you just naturally have a non-American dialect.
Interestingly, the Budweiser and Halloween spots where you're *putting on* accents are actually your strongest easily, barring a slight "hesitation" I could hear from you on "stock up now". These kinda lean more towards character voices, though, so I do like how you placed Halloween at the very end.
The Lego spot requires you to pull back and sell some emotional attachment, as a father talking about his son. The writing even allows for some light-hearted comedy to be worked in. You instead sold this as more of a stiff announcer, which resulted in your weakest read from an acting standpoint, despite having some of your better enunciation.
If you're as serious about your work as you seem to be, I think you'd greatly benefit from investing in studying diction. You also should not be touting yourself as a professional if you're having to list game mods, webcomic fandubs, and Pokemon audio parodies as resume credits. If you were not paid, these are not "employment". I congratulate you on having an agent, but this alone does not make you a professional.
