Nice Job for your first Flash
This was nice for your first flash. But there is a lot of room for improvement. The main character was drawn alright, but you could have added more detail to him. Shading him was a nice idea, hencing the fact he looked more realistic. A great feature you included was the shadow that the main character had. It made the animation look more realistic and more imaginative. As you said in your comments, this animation revolves around a plot that is quite weird but at the same time interesting. I would like to see more of what happens to this character and why the tree dissappears as it apparently did. The music suited the animation very well. It went with the flow of the movie and was a great choice. But there was a lack of sound effects. To have further enhance the movie's detail, you could have added "step sounds" for the character as he walked along the grass. Look for a grass step sound and put it everytime he walks. There is also a flaw that I noticed, but is coherent because of the reason this is your first flash. The main character's walking cycle was a bit awkard and you need to work on it a little bit more. If the main character is a baby, then I suggest leaving it as it is because that is technically the way babies walk, but if the character is a grown child, then I suggest making him walk more coherently to that of a little kid. Another thing to improve on is the background. Next time, try to draw the background yourself because the animation looks a little crummy with the pixelated background. Overall, not bad for your first flash and keep practicing, because practice makes perfect. Hope to see a second part to this, and good luck on your future submissions.
Summary Points: Below average graphics, average style, great suitable music but there was a lack of sound, pixelated background doesn't look well, nice, weird and interesting plot.
