Short and too the point.
Well, welcome to Elite Skills.
Ok, you are probably going to get this a lot, but you should try to make the poem longer. This is a good idea, and I have a LOT of poems about the same thing. The thing with me is he was my best friend, and he knew how I felt, but we are still friends. You should try doing the poem in free verse. You would be able to say what you want without being constricted to rhyme. Besides that, I think it was right to the point. Use that to expand it.
