I have been in deviantart for 12 years but I was not an artist. I never held a brush before, or used my PC to create art, or did any art related stuff before (reviewing music for metalinvader.net doesn't count as art ). I was just here to see art from talented people (some more talented than others) and to feel their joy in trying to express themselves through their art.
A couple of months ago I decided to try miniature assembling and painting. Is it art? I don't know. Am I good at it? I don't think so, not yet anyway, but I hope I will get better eventually. So my deviantart page has its first pictures of something I did. 12 years after its creation.
Point is..never give up. It could be days, months or even years, but when the time comes you will express youself through your creations.
