Fahim,
Your travel snaps are fine personal mementos which will certainly bring you and your family pleasure for years to come (assuming you print them in some form to preserve them).
From an impersonal perspective, since you asked, I've noticed several extremely common characteristics in your photos which I now offer for your consideration.
- Color casts: Your images tend to be heavily blue-casted from the sky. The easiest general way to deal with this is to nudge color temperature higher, watching the blue curve closely. Casts have a way of infecting the entire image. Even if blue is your favorite color you should make an effort to better balance your image colors.
- Color and Contrast: Your images are nearly always far too contrasty. You might say you prefer this as a "style". But it generally looks pretty bad, crushing rich low/mid-tone details and making your images awfully flat. You also tend to amp-up your color saturations to rather garish levels, exacerbating the visual problems of overcooked contrast and color casts.
This landscape is a good example. How's your eye sight, particularly with respect to close/medium work and color vision? The reason I ask is because it's common for
older people with failing close vision to hike contrast and sharpness to out-of-bounds levels. The images look good to them but...
- Composition & timing: You very often identify situations in which good image possibilities exist. But you tend to -just miss- the mark.
That cathedral image is an excellent example. Your radar has sensed that there are posibilities in that scene. But it's a muddle. You've presented no decisions, no anchors. The eye is led, by loud color, in misdirecting ways. What's important in this scene? The people standing in the rain? The cathedral? The umbrellas? We don't know. Little of this, little of that. Photography is all about making decisions, even happy snaps.
I offer these comments constructively for your consideration. You clearly like taking pictures so perhaps you'll find something here to enhance your pleasure.
