thanks all for the comments.
i must admit that although i am new to this camera, i am not new to photography so i cannot take credit in the name of first few shots.
actually i was trying to capture the building in several ways, but the wide angle didnt seem that interesting.
Thanks dude. BTW, feel free to make a test on your lens zooming from 18mm, 24mm, 35mm & 55mm for each shot. Use both horizontal & verticle lines (if any) to test your lens & check if barrel/pin-cushion distortion is noticeable to a certain degree.
In the mean time, enjoy shooting dude.
