Tomato seedlings

Tomato seedlings

I started my tomatoes almost 2 weeks ago. They seemed to be doing okay. Each seed has a little shoot with a couple leaves. But this morning when I got up, I noticed that two of them are droopy and kind of shrivled up. :( Any idea what could have caused this? I spray them all with water every day, and every a few days pour water into the tray. I only have two crappy photos taken with my phone for reference. The two in question are in the middle row, on the outside. The one in the middle seems to be doing fine, and the peas in the top row are okay too. Also, do they look too small for their age? I've never grown tomatoes from seed, so I have no idea what they should look like. Thanks for any advice.
