Alien Cartoon (lines)

Liry asked me to draw her a line art of her alien but in a sort of cartoonish way, I have a hard time drawing cartoons as this means i have to simplify things and reduce details to the minimum so i though on maybe doing something elaborate and start simplifying later. So here is the sketch with all the elements requested.

hope its all is in place and correct as you asked Liriel. Take in mind the line will be thicker after i start the line Art so some details will be lost.

never good simplifying things i guess...

lines ready!

Bonus plain colors:

 it doesn't hurt adding some plain colors to it, let me know what you think and if i should use the lines or the color version for the sticker cartoon tattoo.
