First things first, sharpness is seriously lacking.
Besides the 1st pic, the other pics dont really tell me much that it is in Taiwan. Check out some of the other pics in the travel subforum for ideas on composition and those in travel magazines.
If you really keen abt photography as your hobby.. invest some money on DSLR. Save your time & money on processing. Choose what you really feel like the most & develop. If budget tight, get 2nd hand. Alot of ppl throw out their existing DSLR due to Nikon D200.
