both images look interesting. you can literally see the effort you put into these. you did a great job setting up a scene and it looks like with both images you tried to tell a story. the rainforest one has a ( baby ) tiger standing on the shore looking at the lightning bolt and a woman in the water. i wonder why?
im sure you had something in mind and for sure you got my interest with lightning, tiger and a woman in an unusual place but i could not figure it out. this kind of is the same with the other piece. it feels like there is a story to it which is a very good thing but there is not enough information to make enough out of it to fully comprehend.
if you didnt know - you can use aquarellic pen to sketch in your scene. you can "erase" a sketch line with water and later on you can just paint over them if you didnt do overly thick strokes.
its really nice seeing fantasy themed acrylic paintings and looking forward to seeing more from you
