I actually disagree with Rabbival. It doesn't look static to me at all. First of all, when violins motif is fully completed(you always add a note every bar or something), then third violin(?) starts playing, and then again it starts from a very short motif and becomes longer and longer. Then same with cellos, and then oboes, but the texture is always different. Then modulation is placed perfectly at about 2:30, when flute starts playing and then from all these staccato motifs it finally sums up to massive one, main motif. And then the ending is really beautifully made from the first motif! I think it is full of energy and happiness. I really liked this piece, good job!
