thanks for commenting on my Megan Fox Caricature! I really appreciate it.
To answer your question I guess you need to be active on deviantart in order to get noticed. Try to add some favs and comment on a daily basis.(If you can) This will increase your page views and will draw attention to your art. And also try to advertise your art more. (In comments, in messages, clubs, etc.) Your work is good! Keep up the good work!
