I didn't submit anything for like 2 years. I love looking at stuff on DA, but the thing is, there's so many great artists, professional illustrators, photographers, etc... that I almost feel stupid for putting up stuff on here. I joined DA in 2009, I submitted most of my stuff during the first months, and then I just stopped... looking at nice stuff was great, but then it became almost frustrating, cos I wanted to do nice stuff too,... So, I've decided to be less critical and hard with myself, I play with my camera or with a pen cos I like it, I think it's fun... yes, I wish I could be better, but I shouldn't be competitive, taking pictures or drawing is something I do for fun, no need to be ashamed of my deviations or frustrated.
Your art is fine, it looks great, keep working at it, it'll improve. If you like it, that's good enough fro us. Please don't worry about criticism, it helps an artist grow. Keep sharing.
