I looked at the image to see what i could do with it and it came to my attention that the arch is the focus point in this environment so it was this i need to make more unbelievable.
I started looking at stone sculptures or carvings as i thought as the arch is made of rock, this could be the path i go down. Here is just some images i found.
I thought maybe i could sculpt something like in the photos into the rock or something like a mermaids tail as this would fit because of the curvature of the arch but to me this wouldn't really make it unbelievable to an certain extent.
I then thought that this wouldn't really make this arch unbelievable as there is plenty of carvings and sculptures all around the world. so i decided to look at what the arch looked like already and to me it either looked like a arm or a leg.
With this i decided to make it into a stone giant, so all i needed to add to this was some arms, a torso and a head.
