The first few sentences were brief, but it caught my attention for reminding me of the start of a new season. :') I wondered why the author didn't sustain with the style of the first paragraph, though. Short sentences can create an interesting rhythm to read with.
I felt like Sammy's transition from being isolated till approaching the girl was slightly abrupt; I would like to know more about Sammy's thoughts when he saw that Anna was crying.
Towards the middle, there was more tell than show, so I would love to see how the writer would show him not reaching out towards the other children – maybe his view when staring from afar? I would have also loved to see more of how Sammy's magic changed his appearances according to his moods.
A promising start! I was intrigued by the fact that this children's piece was clearly aimed for slightly older children. You have ideas about your writing style, which is great. I would've loved to see more of your style throughout your piece – don't be afraid to experiment!
Some suggestions ahead! You can choose not to follow them if you wish; I am just placing my thoughts here in the hopes of sparking your creativity with this piece. Test the limits of your style! :)
I noticed that you ended off each scene with a colour that brought across a certain mood and thus, a certain suggestion about Sammy's character; I would've liked to see this metaphor used more throughout the piece! You can even experiment with shades.
If you'd like to be more creative with the transition of different scenes, you can give each a brief title to signal to the reader that some time has passed, e.g. something to do with the main colour of each scene: green birthday in May to blue waves in April, or orange company to lonely blues (not very good examples, but you get the idea!).
Since the title was "A Friend's First Smile" and the first few sentences had the word "first", maybe you could end off with "first" in a sentence somewhere near the end of the piece, so as to make the title more significant. (It might just be me who feels like this makes the piece feel more complete, though.)
Once again, I enjoyed reading this piece and I hope to see you write more! :D
