Are these photos any good? (for young person considering photography career)?

I'm 14 years old and I love photography. I'm considering photography as a career when I'm older and was just wondering if there's any potential in these photos (the link is below).

I want to buy a 50mm lens but my camera(Nikon D3100) doesn't have a build-in focus motors, so I need to buy a 50mm AF-S that has the motor inside.

How to take great pictures with a Canon Powershot SX1?

Has anyone ever used this camera before? I'm just starting photography, so I don't know how that much. I want photo quality like the Nikon D90, but the Canon Powershot SX1 doesn't seem to have that… Or at least, I don't know how to take good quality photos like that. Help? I don't even know how to change the exposure or shutter speed! I really need good quality photos. I really like the soft hue to the Nikon D90 photos.

Can i use pentax k1000 lenses on any nikon or canon DSLR?

I want to buy a DSLR, though which one I'm still not sure. I read somewhere that even Pentax DSLRs need an adaptor for using the old screw-mounted lenses my k1000 uses. Can I find adaptors for using my lenses on, e.g, a Canon Rebel or a Nikon D3100? I'm a medical student and I don't really have the money for buying new lenses, so any help would be greatly appreciated.

Is there any Sony Alpha camera that compares with the Nikon D90?

I want to make the jump to digital from 35mm. I like the D90 best so far. The only problem is the price of the D90 with lenses. The Alpha also has one advantage for me: I already own two lenses (so I will only need to buy the body to begin using it). They are Minolta AF (Minolta A-mount? - currently on a Minolta Maxxum 450si). I'm told that they work on Sony's Alpha cameras. All my previous SLRs have been Minoltas and I love them, so when I was told that Sony bought and uses Minolta's technology, that was a huge plus in my opinion. Is it true that Sony bought Minolta? Is their quality as good as their reputation? Or is the D90 the best balance between price and features for a first-time DSLR (but not first-time SLR) owner?
