Are my photos any good? - 1

Http://web.stagram.com/n/ellenk5113/

13 years old, aspiring photographer. I usually take pictures with my Nikon and filter it with Instagram… I know that I'm nowhere near professional level (and that Instagram isn't exactly known as an app for pros) but I'd love to hear feedback and critique so that I can improve :)
Added (1). @Angela: Thank you for the feedback! You're right about my needing actual filters. I'm not entirely sure how or what program to use, however, but I'll try not to rely on Instagram so much :)
Added (2). @fhotoace: Thank you for providing the link, I'll try to incorporate what I can understand into my photos.

Broken camera sensor?

I have a nikon d5100 and chances are the sensor is broken because all my camera can produce is black images yet it works perfectly fine (can autofocus/ adjust settings perfectly)… but to me at least there is not visible damage inside or outside of my camera

and if it is would it be covered under the warranty or would it be cheaper to just buy a new camera over the repairs if it is severely damaged?
Added (1). The live view also shows up black but the screen works, so its like the camera just registers black, its not that i dont know how to adust the settings. …

I'm looking for a digital camera with quick shutter speed?

I'm wanting to spend about $200 and under. I dont really care about certain brands either. Megapixels arent that important but I would like a decent zoom, at least 5x zoom. I bought the Nikon S3100 almost a year ago, and it's just a horrible camera.It lagged like no other and the pictures were just a mess.

My biggest concern is the time that it takes to go from one pic to the other and a decent price. Thanks for all your suggestions! I'm looking forward to purchasing a camera within a few weeks!

SD card works on camera, but not computer?

I have an SDHC Card, and I use it with my Nikon camera almost every day, and every day I put my SD card into my HP Pavilion laptop and it works, and I store the pictures in different folders on my computer. Recently, I have to push the SD Card in pretty hard until it reads, but today, no matter how hard I try, it won't work. I also tried the SD card in my brother's laptop, and it wouldn't read.So the card won't work in two laptops, but it still reads perfectly fine on my camera. I don't have the USB for the camera.

I just got my Nikon 21x zoom camera yesterday (not a new one) and it was working fine, it just dies really fast.
Anyways, I took a picture, but then it just goes to a black screen, still on! But black. Whyyyyy? D: I switched the batteries a jillion times, erased some pictures and videos I didn't need but still… same thing.
