I apologize for being a poor critic of portraits, but I find critique particularly difficult in this arena. I'm not much of a portrait photographer myself, and I don't know most of the finer techniques of lighting and composure. All I can offer is what I feel about the photo in general.
The pose in this photo has it's 'cuteness' and the subject (yourself) seems relaxed enough and confident with the idea. IMO, there are two problems in this portrait that have probably been discussed in any commnents you received on this photo. 1. The light is flat. It would appear that the on camera flash was used, which is a rather poor source of lighting for a portrait. Some of the best portraits you will ever see may be artificially lit, but they won't 'appear' to be in most cases. They will have a natural light feeling to them. 2. As you mentioned, the processing is a bit heavy IMO. There are two levels of 'great' post processing... the kind where you can't tell it was done and the kind where it creates the mood. This one, to me, feels forced. It appears that areas of the image suffered in order to get a problem in exposure (or something else) fixed.
Try experimenting with natural light portraiture... I'm sure you will enjoy it and the results will be excellent :)
blue channels seem to be oversaturated. background seem to have an off-white or beige ton to it which somewhat matches the contrast levels of the skin. this tends to mesh the background and the model to the same tone, instead of separating the subject from its background
colour seems a little muddy, perhaps thats from trying to isolate the blue? think the blonde hair could have been brightened to give a nice accent to the eyes.
i'm not sure the high contrast feel here is the best way to go for this type of image. i like tht it brings the eyes out, but it crams the skintones and hair into the same visual space.
although i can tell it hasnt been desaturated the color is not too present, also bouncing the flash off of a wall or putting some diffusion on it might help..
Cute, Love the pose and the over all feel. The light is way too strong. Need to tone this down with the contrast of light hair/dark top. Great blue eyes.
Full on flash is tough to pull off, it robs the face of flattering shadows and exposes flaws in the skin. it also looks as if you are slightly back focused as the hair is sharper than the leading edge of the hands and mouth. im sorry if this comes off a harsh, just trying to point out room for improvment.
