Personally, I really like it the way it is. However, I could understand why you would want to color it. Be careful though. The colors could take away from the beautiful lines that you made. I feel as though the coloring of this piece would have to be very light. For example, maybe you could consider using watercolors or color pencils.
i think you're right. watercolors sound good actually i think it might have a nice affect. im not very good with traditional coloring in general so ill have to be very careful. thank you so much for your advice!!
