Yes, the photos are of good quality and the images fit well with the theme. Pictures chosen are good and flexible for layout of the text. Last picture mobile phone, maybe find a better quality picture?
Yes, all photos include Edna Mode and the font type works well too with the bold and serif style. The red text in some postcards are also nice to see.
Yes, the placement of '-Edna Mode' in every postcard makes sense and is considered.
Yes, same font and quality of photos are used for every postcard.
Aesthetic drives the concept
Helping, but the first one in desktop form, the font could be black because the white blends with the background a little bit
For the first postcard, the picture is the priority but for the other two postcards, the text is working as the main priority. Probably due to the color and large font for postcard 2 but the negative space and emphasis for postcard 3.
Working with complement, third one working well with contrast of light yellow image and black font. The first one is a little conflicting because type is white and the walls are also light.
For first postcard, the picture is a foreground. Other two, photos seem like the background. 'Edna Mode' in all of the postcard seems a little hidden/part of the background if that was intentional
Transparency not used
Text moves around well and fits into places where the eye goes
Only in the first desktop postcard with the white font with light background
Yes, except last mobile postcard, the photo could be of better quality. It stands out from the rest because of the quality
Yes it seems possible
