Do you have any photografic experience?
If not, your pictures probably won't be any better on a DSLR - however, if it encourages you to take more pictures and practice then by all means go for it.
You really can't go wrong with anything from Canon or Nikon.
This has definitely been asked 400000 times in this thread, if I want an entry ish DSLR that’ll take decent enough photos, what am I looking at?
