I'm not very sure about the designs. I would like you to do some changes:
#52:
"bis" the same as #36 (a bit up, more joined to "Sopesa")
Plant only a bit above letter "s", the same as in letter "e" (only touch letter a little).
Or plant the same as #34 (introducing it in letter "o")
Turtle in dark green
Remove bubbles and aquarium (all the draw above "Sopesa".
#28:
Remove bubbles (keep the aquarium, no remove)
Turtle in dark green
#36:
Plants the same as #52 after changes. The rest the same as original.
Thanks.
