well, please don't get attention about the star of this rate. (i don't really use these), really.
for the tone well, it's cool, but it's too conrtast from their originality, some best part will gone if you always convert it like this, (maybe) why don;t you try simple tone but still keep their original colour?
for the triangle, that was so unique thing, but maybe you need to make this thing (just like this triangle), but in a theme, (a form is depend on their theme, like circle, or other).
but totally you're so creative and your gallery is awesome, keep your good work!
I really like where you went with this; the deep contrast between the different styles, however I would suggest making the change between them a little more subtle, fading each into each other possibly.
The colours used are gorgeous, creating a really nice difference between effects. My only confusion is over the bottom part of the image where I'm not entirely certain I like the change to the dress but it certain does stand out and make this unique.
I really like that the triangle for the original image clearly keeps the face original, almost like the subject is seeing the changes around them, as I assume is the case with the title of the image being Exclusion which is a really interesting idea to go with.
With this type of image I would imagine that most people would change the effect of the person and keep the background/surroundings as they were originally, so I really like the opposite effect you've gone for.
Also, not being able to quite make out what the surrounding objects are, it helps to keep focus on the subject, which is such a great technique, making the image all the more interesting and giving a really nice impact.
Overall, there are a couple of things mentioned which could be added/changed, but in full this is a wonderful image which makes the viewer really contemplate the meaning. Great image!
