You should!! You have me as a fan, and I know you'll have lots of other people here on deviantArt who love your art and will support you!! c':
I'm sorry you didn't get to fulfil this passion until recently, but yes, everyone starts somewhere!!
I can try to help you out by sharing your account on mine!! I don't have many followers who really look at my stuff, but I have a few good friends who'd definitely love your work.
Ahh!! I love robotics, but I could never fulfill that passion of mine. I'm no good at math, but building is amazingly fun to me.
