[FREE LINEART] Butterfly

This is a line drawing I made a few years ago; around 2014, I think. The download file contains a .PSD format with two layers (1st one is the lineart and 2nd is just the grey background.)
What you see in the preview image is just my trying to make the preview less so-emptily-grey/bland. :'D

 You can use this line drawing for practice purposes only and yes, you can upload it anywhere you want; but please do credit me for the line drawing.
 And if it's not too much trouble, I'd like to see the coloured drawing you make, so you can send a note to me containing the link or just leaving it on the comment section bellow.

Go have fun with it!
