Dragon vector art

This is one part I really struggled on when tracing the dragon in Illustrator. I had a problem at this part because it was a very tricky part to trace because of all the curves and stuff.

This is the picture of the dragon without any colour. It took me really long to complete this piece of art. Especially because I had to trace both sides of each line.

This is another area I struggled on because it was I very difficult part to figure out how to trace. Then eventually I thought about it and I figured it out.                                              

This is the final product of the sketch that I was tracing in Illustrator. This is a dragon and now its fully coloured.
