Not bad. It didn't feel like a whole lot happened, but it was a fun flash anyway.
Here's what I liked:
-Background art was very pretty.
-The music was fitting.
-Most audio was alright.
-There were some funny moments.
Here's what I didn't:
-Some of the anatomy looked odd, particularly Saria's running in the forest.
-Diggs voice was a little hard to understand at times (I shouldn't NEED subtitles to understand someone speaking English, but in this case I did), and his lines weren't delivered with much enthusiasm.
-The flashback with Mido was confusing, I honestly couldn't tell what happened or why it would make Mido mad.
-Why was Diggs the only character whose name showed up as question marks when he spoke. Saria had already mentioned him in the previous scene so it wasn't hard to figure out who this character was. And when you did officially introduce him there was nothing significant about that moment. In my opinion you should have simply put his name there from the start if you weren't going to do anything with the reveal.
-Not much happened. It felt like more time was spent on a game of tag than moving the plot forward. As a result there's not really anything that grips me and makes me eager to find out what happens next.
Try to give some sort of plot hook in the future. It's good to establish your hero's goal as quickly as possible. Even if it's only a piece of it you should hint at what direction the series will take. Aside from Link having something come up with Mido I don't really know what's coming down the road. If I were to base my expectations of this series on this episode I'd assume that this will be a slice-of-life series about Link's everyday chores and such which is, to be brutally honest, not something I'm excited to see.
