I spent a lot of time on these and am very happy with the results <3 I added you sketch so you can look at them since this is just a preview
about the lines
.Includes adult,teen and pup/calf (didn't know which) lineart
.Please do not mess with and shading lines or eye stuff
.I did not color them in but if you really want I can but feel free to do it if it wins of course but no shading I already did that
.The horn is not optional but if you want it to be like narwals where the males have a horn/tooth and the females don't I can make them on a separate layer
.Don't mess with my sig obviously XD
.I changed there tails so they are like a whale tail and they have no back legs. There front legs are connected to whale like fins kinda like a back. Also btw they are air breathers in case anyone was wondering
.Feel free to ask me to add more stuff or change anything
edit:I'm posting them all
