I have twitter and instagram . Both are dedicated art accounts . I ' ve had a couple of commissions through instagram but to be honest I don ' t do that great a job with it I use it a little like a poster board where I put my art with information but don ' t interact with other people particularly . It ' s got me , slowly , to 500 followers . I ' m far more active on twitter in general , and interact more with others . I ' ve reached 1 k followers and had an art agency contact me , so whilst I haven ' t made any money through it it ' s working better for me overall so my guess would be that interaction is key ! Like others said , use lots of tags , and also reach out and comment on others ' work too ! I should probably follow my own advice p
