Op104 Symphonic Overture (sound effect adjusted)

hello everyone, this is an old piece I composed months ago, when I am free recently, I adjusted its sound effect in Cubase, hope you like it, and every commentation is welcomed.

What's this overture to? I know that not all overtures are written for a specific event of play but you must have a picture of something in mind when you wrote this. Also the theme sounds oddly familiar though I cannot name any other piece at this time.

You accomplished the "symphonic part" quite fine, with often very transparent textures. However, isn't it more an orchestral "Theme and Variations"? "Overture" evokes other expectations in form and substance than your opus fulfills. Just a minor quibble: You could try other orchestral soundfonts, like e.g. Sonatina, if they are compatible with your software so your music will sound even better. The Musescore fora offer some good discussions on soundfonts.
