Nice! It seems like the pterodactyl is casting a shadow on the sky, and if it's supposed to be another bird, try making it smaller and more to the left. Good luck!

EDIT: Good change, it was pretty confusing because the low contrast suggested distance, but he was right next to the other pterodactyl. Good luck!!

scatter effect is very well done.. almost feels like I'm looking at the journey to the center of the earth (old version) good luck author
