Ok, its been a long while since my last one and after many stops and starts I've finally finished another. Made this one significantly bigger than the others. This time I paid special attention to the floor, since in my last attempt it was not well defined.
Looks pretty good to me and I like the low angle/perspective you chose. The building on the right, and its shadow, could stand be a bit darker maybe, to contrast more with the sunlit areas, but, overall, I think you did a great job.
Love the frog POV, great overall design. The sky could benefit from some clouds or at least a gradient of some sort, it looks empty as some have pointed out before.
Since you mentioned it I do agree the floor is very well defined but I'll also echo that a cloud or too could help the sky stand out more. Still I like both daytime and evening versions so well done.
