Welcome to the forum. I hope you learn as much from this place as I have.

Just some quick thoughts for you. It is really useful to let other members know what equipment you are using so when they are critiquing your photos they are aware of what options etc you have at your disposal. For example, your portraits capture lovely expressions on your subjects faces and it would be great to be able to enhance these by ensuring your background is blurred and therefore not distracting. If I knew you were using an SLR camera I would suggest you use a larger aperture, therefore creating a shallower depth of field. If you are using a point and shoot, I would know this isn't necessarily a useful suggestion and would suggest that you move your subjects further away from the background to ensure it is blurred. Does this make sense? anyway, letting us know what equipment you use is a valuable piece of the learning puzzle.

Also, it is a general rule of thumb to post no more than 5 images a day (and comment on just as many) and generally if you want in depth critiques (that are not simply about comparisons between the photos) I stick to one, maybe two photos at a time. Some exceptions to this might be if the photos are a series or like I said above you are looking for some help to work out which is the better shot etc.
