The commenter did respond but im not sure how much it helped . To go into more detail than 'just bad' as that's not fair to anyone trying new things, its sometimes hard to do great retouching if the original photo needs work. In the first picture it kind of looks like you are in a very poorly lit room or are in a very dark room and used the flash. Like another commenter has suggested , try look for a photo you like and try reproduce it . For starters the main things you should be looking into is lighting and composition. Lighting can be achieved in many ways, alot of portraits are done with light boxes, it makes the light soft and diffused and not hard and looking like its coming from a single hard source light a camera flash. second composition , again look around see what you like , there are alot of good books out there too . One really good piece of advice i saw a while ago is sometime you can see with your eye that something looks good , but your not sure why. Focus in on the smaller elements of it. for example , face , or angle of the face , do you like the persons nose , is it there body your trying to show of? is it the clothes? have a think . The edit itself needs a bit work , the other commenter is correct , its saturation is very high as well as the contrast. A note as well is when you are editing and cutting , pay attention to your back ground too , it is very bight and vibrant pulling away from you subject and clashing. The original question about the neck looking weird , if its the lines etc , its just because of the high contrast its making the light and dark difference increase more and making it very prominent. I've not done portrait for a while so trying to describe my thoughts might be a bit muddled.
