blending options, change of brightness and contrast, changing highlights with the dodge tool made the creature blend in to the sea and into one animal instead of loose images copied together.
step 6 of 7
Only the beast is a bit lonely so added a little sea animal.
Needed to blend in more so made it smaller, used blending options, duplicated layers and blurring to blend it into the background and whole of image more.
Added some more bubbles and there the little fish scared by our creature!
