IS THIS FOR REAL.. ¿!!

OMG..! I was amazed and surprised at what the sketch lines was turning into.. !

I am not an artist, but I'd like to be one.
Cool arts really gives me the urge to create one, but I couldn't.

But today at work, during my leisure I logged on to steemit and just stumbled on one of @opheliafu works, I looked through all her work and they were cool, they gave me desire to really try something.

I had no pencil with me, no color, no clean sheet. But I felt like trying my hands on something, anything.
So I took a rough paper and with my blue pen I started sketching, at first I didn't even know where I was going with the sketch, but when the lines and curves began to make sense, then I was OK this is what I'm doing.
Here is it.


I had no idea it will get to this, I know it's not great. But this is really the first time I'm trying to draw. And I really really want to improve.
So guys I will appreciate if you point me a direction to really improve this skill.
Thanks.
