hi everyone, im not a professional in retouching but im learning by reading tutorials and trying things with photoshop, well talking about the pictures

the First one (summer):
-i took off some hairs in the forehead
-took off hairs from the eyebrows
-reshaped eyebrows and replaced the left one
-fixed the teeth (replaced some and whiten)
-D&B to improve bone structure
-drew eyelashes
-fixed makeup
-improved contrast
-put a white background

the second one(80s):
-took off some hair from de forehead
-replaced the left iris
-drew some eyelashes
-fixed eye liner
-reshaped the nose
-fixed scars and blemishes
-adjusted colors and added contrast
-D&b
-reshaped eyebrows.

well hope you like my works, i didnt took the pictures they are property of
stock from deviant art and i've permission to use them...

Heres my opinion.
First one: Eyes and skin look good. Generally skin color and contrast too. But some things looks strange to me... fo example lips... their's perspective looks bad... also the teeth dont fit.
Second one: Better then previous, but here lips looks strange too... on the original foto they dont fit to image (they looks like was badly added to photo), and after your's correction this effect goes even stronger -> top one is even more not realistik than bottom ;).

Except that, generally good work.... they looks a lot better than originals.

thank you for the critique, i took a second look to the first girl and you were right about the teeth so i fixed that, hope its better
