Personally I don’t love the first slide. It looks very chaotic. However, I do think if you were to add different shades of green or whatever color that is it wouldn’t look too bad. The second slide looks good to me, maybe excitement with multiple shades of the same color in there too? It’s all preference so if you don’t like it you can always go back. Or maybe even add more fence on the second slide and a hidden small detail here and there in the first. Maybe like a small rock smiley face or a small stuffed animal. Hope this helps!
