The first pic is cool I must say, having an MAS plane stuck to a building... If you wanna take pictures of plane, speak to Terence, he can definitely advise you on this...
The equipment can only bring you so far - the rest of the photographic journey is done by you.
I like the 2nd (terrapin) and 3rd (park) pics
2nd p : nice lighting, and manages to catch an affectionate mood. can do with a bit of cropping at the bottom, but this is just a minor thing. good job here!
3rd p : nice and serene feeling conveyed, and you did good in your composition
keep it up!
sorry, just my pet peeve, the horizon was slanted in #3.... i took the liberty of correcting it, hope you dont mind :
