Welcome to the photography section of GTP Shant J.
Please don't think me overly critical on any shots, I promise I'll only give constructive feedback. Sweet Chrissy present by the way 👍
I'll start with your first post.
The first shot lacks focus. I can see what you are trying to accomplish with the shot and it's whole east meets west thing, but there are too many objects for your eyes is drawn to. I think it would have worked better if you split your subjects up. Keep Buddha with the headphones (sweet ides by the way, I'd imagine he is listening to Prodigy

) as a separate shot to the philosophy book & incense thingys.
Shot 2 & 3 are partials of subjects. There is usually not much wrong with having a partial of a subject (I do it all the time) & I can see that you have been boning up on your 2/3 golden rule when it comes to composition (good stuff), however neither of these shots work for me. The building behind the tree is very distracting in the 2nd shot & in the 3rd shot, the building lacks any real point of interest. I can't make too many suggestions about shot 2 but for shot tree, I would recommend with trying to find a spot to shoot from that makes the building level with you or shoot a smaller detailed part or the entire building.
Now onto the next post. I like the ideas. The composition is good as well. These shots almost made it. But I have a handy hint for you. I love the use of fill flash, it can be very handy. What your camera is most likely doing (if the Nikons are anything like Canon) is that it will revert to a shutter speed of 1/200 if the flash is on. So what you end up with is some over exposed backgrounds. What you need to do is to reduce the aperture (or make the numbers higher) so that when you take a light reading of the background, it sits below the 1/200 shutter speed. Then when you take the shot of the subject (like the parking meter and the oversized decorations) the background isn't all blown out and white but properly exposed whilst still having the subject in the foreground "pop". Also be careful of the flash flare in objects, it's visible in both shots.
I hope some of that made sense to you. As I said, only trying to help with some constructive feedback. Keep shoot & keep on posting them up as ou have the right idea, just need to refine the execution a little.
