Composition, timing, and colors on the first two are excellent.
Third one doesnt stand out all that much to me.
I really like the angle and composition in the 4th one, his front wheels a bit hot but its really no big deal, its still a really good photo.
The colors and timing on the second to last one are soooo good. Also, i know ive said it alot already, but the comp is really good, too.
The last one looks almost like film to me? Idk if thats what medium format is haha. The timing is literally perfect too.
Such a gooood update. I cant even find anything to critique haha.
