"Just stop with your crappy animations already!"

I like it. I think it would have benefited from a little more variation, though. When the other bird landed next to the first and started singing, it was difficult to tell he was singing at first. Then, she seems pretty much unresponsive up until it was her turn to start singing. Having her acknowledge his presence when he initially lands, then turning away as he starts to sing would have been a much more interesting choice.

It switched between the same handful of perspectives through the entire thing and though it did change, it didn't really feel like it. Try messing with really bizarre perspectives or having the camera "move" as you animate.

You're definitely improving. Can't wait to see what you make next.

I'm hardly in a position to judge, but I'd say that it's a little bit static, not just in movement of the actual objects in it, but also the camera's perspective. Still though, I understand that in all fairness, it's a pain in the ass to draw all this.

Besides that, everything else is either fine or good.

Basically, I said the same thing as Slog Bait.

Seems good. Watch the asdf movies on youtube for some inspiration

I just rewatched it and noticed a lot of tangents. This is visually unappealing and renders everything completely flat. Also, isometric perspective is generally not the best choice for something like this. If you're not comfortable with your current skill level, switch to atmospheric and 1pt/2pt perspective. It won't be the best thing in the world but it will help everything significantly.

Oh! Also, an idea for what you could have done when the pigeon looked at the person indoors. Perhaps we could have been looking at this person in the reflection of the pigeons' eye one of those times. Maybe have it start where she looks over at the window with the figure's silhouette, then switch to the reflection in the pigeon's eye before closing it and bowing her head.

I had no idea about what the 1pt or 2pt perspective is until you mentioned it. In fact, I know little about drawing

The ideas in the second paragraph are not bad.
