Here is the tricky thing about posting images that are your "portfolio" images. They need to be stunning. Your best of your best. These have to be spot on. And unfortunately you have some problems with the ones you posted. For example your first shot in your portfolio - it's a nice image of the lady - but it has some issue. To the right of her hair is the sign in the back that has an almost neon relish color to it. It very much distracts from the image. The whole background is unfortunately too busy to truly isolate on her. All the issues are fixable, and should be fixed if these are going to be presented as portfolio shots. Another image - the one of the young lady, simply is processed too flat. To bring it to life some curves work would really help it.
Honestly I almost stopped there... but then became curious about your blog. And those shots are appropriate for a blog. Not bad at all for what they are intended. So just really make sure if you are putting out "portfolio" shots, they really are images that you have done your absolute most to make sure they a perfect, or near perfect. Remember, very few portfolio shots come out of the camera that way. They will need to show you understand the total workflow of producing high level quality shots.
Keep at it.... your off to a good start.
