Always good to have a new story in the Literary Society.
Even though we know barely anything about the character yet, you've done a fairly good job already at showing his personality and how he appears to others.
Although, most of the sentences near the beginning and the end seem really short (4-6 words apiece), perhaps you could join two of them together? For example,
"Russell was a high school student. He was often made fun of."
=
"Russell was a high school student, one that was often made fun of."
"He stopped a foot away from the bolt. He reached out a hand."
=
"He stopped a foot away from the bolt and slowly reached out to it."
