There isn't necessarily anything wrong but they don't look in prime condition. Snowdrops and pine trees do not naturally associate but I would not have thought a few pine needles would do any harm. Some of my snowdrops got a bit battered by the strong winds in January and February but should recover next year. I suggest you re-pot yours in fresh compost when they go dormant and take the opportunity to inspect the bulbs, isolating any unhealthy ones.
