I think the composition is a bit too muddled with all the different types of lines going through (the branches and sticks). If it were the same tree and same type of lines, I think it would help the minimalism (reducing the elements). The photo looks oversharpened.
This is too crowded picture to be minimalism, the picture isn't clear enough either, but I have to admit that I would like to be there, in my country there are no frogs:-(
The trees out of the way and the frog low to the right on the picture would have made it much better. Best wishes for continuing photograpy!
Great pic of the frog (toad?), but the image is a little too busy for me. Would have worked better for me without the sticks/brush in the foreground, but I know that sometimes that's the only way to get one of these shots.
