I rarely find these kind of wide angle reflection shots work as there isn't anything to hold the viewer's attention unfortunately. You need to hone in on something of interest, looks difficult here but maybe zoom in on the birch trees to the right hand side, especially if they change to their autumn colours before the surrounding foliage. Or having looked again those fallen trees to the left, you'd need special conditions or lighting to really pull it off. A white vignette is best avoided
