I like the 4th girl as her contrast, warmth, and general lighting seem better. If not originally used I would try fixing the photos as raw and then when ready do the re-size last paying attention to constraints. I like the 5th girl but my own tastes would rather see the image a bit warmer. It’s easy to say things but I will say that picking, setting, color, warmth, etc for the panel is a difficult task. I’ve done some myself and overall I’m not happy with them for one reason or another, composition differences between the photos maybe. I think 1, 3, 5 are a little too washed in some areas (but that’s my own taste and you or others may not share that view).
