I unlocked for myself some new achievements in painting 'cause I worked hard all this time

Hi! This's my news: all this time I draw by hand (acryl and guache on cardboards) and also I buyed a pretty-looking graphics tablet (all my previous works was drawed by me by mouse). This current work with these girls is about air and freedom and relations between humans. Because we all need them really.

Also I have a question to all of you. I draw some nude things but I doubt do I need to tag them as NSFW? I see that nsfw tag is used usually not for arts but for bad-quality porn shots and eh what do you think about it?
