There are some nice pictures here - and Tareq, I think this is the first time I have seen you post a picture - nice job, do not be too quick to put yourself down!
Only suggestions I would make are to take your pictures while there is still colour in the sky - very dark blue - rather than inky darkness.
also perhaps to use a graduated neutral density to hold back the sky detail.
I hope you will post more pictures, always you are discussing equipment, it is nice to see what you do with it!
first shot i took in Leabnon, and i don't know about photography, and took without tripod as well.
second shot i took with my new camera and lens, but i used CLP instead of ND, i got ND but really i don't know what is the benefit, and i thought it is just for landscapes in day time, and what do you think? should i try to shoot with my 16-35 or 10-22 on my 350D/30D? using ND as well?
I will have more photos later as i feel lazy with hot weather and i am waiting to get better weather soon, and i may travel to Europe, so i have to learn and practice before i travel, and when i see all these great amazing photos i feel myself like all my photos are just junky.
