What do you find different with digital illustration from drawing by hand?

using illustrator is a little more complex than drawing by hand, however there are more benefits to using illustrator. for one when you would constantly have to erase and start over to get a curve right you can do it much faster by using the pen tool and twisting the node a little before releasing it, and using the pen or pencil tool makes tracing a much speedier process for art pieces you want to recreate a part of it. also with illustrator it is a lot less frustrating to transfer your art piece to another platform to add effects to it because most of the effects are already in illustrator, and begin an adobe product what's done in illustrator can be transferred to and improved in other illustrator products. in addition to that color selection is much easier.
